If not, see . - -============================================================================ - -I. OVERVIEW: - -This is Version 4.0 of the EDT Emulation for Emacs 19 and above. -It comes with special functions which replicate nearly all of EDT's -keypad mode behavior. It sets up default keypad and function key -bindings which closely match those found in EDT. Support is -provided so that users may reconfigure most keypad and function key -bindings to their own liking. - -NOTE: Version 4.0 contains several enhancements. See the -Enhancements section below for the details. - - -Quick Start: - -To start the EDT Emulation, first start Emacs and then enter - - M-x edt-emulation-on - -to begin the emulation. After initialization is complete, the -following message will appear below the status line informing you -that the emulation has been enabled: "Default EDT keymap active". - - You can have the EDT Emulation start up automatically, each time -you initiate a GNU Emacs session, by adding the following line to -your .emacs file: - - (add-hook term-setup-hook 'edt-emulation-on) - -IMPORTANT: Be sure to read the rest of this file. It contains very - useful information on how the EDT Emulation behaves and how - to customize it to your liking. - -The EDT emulation consists of the following files: - -edt-user.doc - User Instructions and Sample Customization File -edt.el - EDT Emulation Functions and Default Configuration -edt-lk201.el - Built-in support for DEC LK-201 Keyboards -edt-vt100.el - Built-in support for DEC VT-100 (and above) terminals -edt-pc.el - Built-in support for PC 101 Keyboards under MS-DOS -edt-mapper.el - Create an EDT LK-201 Map File for Keyboards Without - Built-in Support - -Enhancements: - -Version 4.0 contains the following enhancements: - - 1. Scroll margins at the top and bottom of the window are now - supported. (The design was copied from tpu-extras.el.) By - default, this feature is enabled with the top margin set to - 10% of the window and the bottom margin set to 15% of the - window. To change these settings, you can invoke the function - edt-set-scroll-margins in your .emacs file. For example, the - following line - - (edt-set-scroll-margins "20%" "25%") - - sets the top margin to 20% of the window and the bottom margin - to 25% of the window. To disable this feature, set each - margin to 0%. You can also invoke edt-set-scroll-margins - interactively while EDT Emulation is active to change the - settings for that session. - - NOTE: Another way to set the scroll margins is to use the - Emacs customization feature (not available in Emacs 19) to set - the following two variables directly: - - edt-top-scroll-margin and edt-bottom-scroll-margin - - Enter the Emacs `customize' command. First select the Editing - group and then select the Emulations group. Finally, select - the Edt group and follow the directions. - - 2. The SUBS command is now supported and bound to GOLD-Enter by - default. (This design was copied from tpu-edt.el.) Note, in - earlier versions of EDT Emulation, GOLD-Enter was assigned to - the Emacs function `query-replace'. The binding of - `query-replace' has been moved to GOLD-/. If you prefer to - restore `query-replace' to GOLD-Enter, then use an EDT user - customization file, edt-user.el, to do this. See edt-user.doc - for details. - - 3. EDT Emulation now also works in XEmacs, including the - highlighting of selected text. - - 4. If you access a workstation using an X Server, observe that - the initialization file generated by edt-mapper.el will now - contain the name of the X Server vendor. This is a - convenience for those who have access to their Unix account - from more than one type of X Server. Since different X - Servers typically require different EDT emulation - initialization files, edt-mapper.el will now generate these - different initialization files and save them with different - names. Then, the correct initialization file for the - particular X server in use is loaded correctly automatically. - - 5. Also, edt-mapper.el is now capable of binding an ASCII key - sequence, providing the ASCII key sequence prefix is already - known by Emacs to be a prefix. As a result of providing this - support, some terminal/keyboard/window system configurations, - which don't have a complete set of sensible function key - bindings built into Emacs in `function-key-map', can still be - configured for use with EDT Emulation. (Note: In a few rare - circumstances this does not work properly. In particular, it - does not work if a subset of the leading ASCII characters in a - key sequence are recognized by Emacs as having an existing - binding. For example, if the keypad 7 (KP-7) key generates - the sequence \"Ow\" and \"O\" is already bound to a - function, pressing KP-7 when told to do so by edt-mapper.el - will result in edt-mapper.el incorrectly mapping \"O\" to - KP-7 and \"w\" to KP-8. If something like this happens to - you, it is probably a bug in the support for your keyboard - within Emacs OR a bug in the Unix termcap/terminfo support for - your terminal OR a bug in the terminal emulation software you - are using.) - - 6. The edt-quit function (bound to GOLD-q by default) has been - modified to warn the user when file-related buffer - modifications exist. It now cautions the user that those - modifications will be lost if the user quits without saving - those buffers. - - -Goals: - - 1. Emulate EDT Keypad Mode commands closely so that current EDT users - will find that it easy and comfortable to use GNU Emacs with a - small learning curve; - - 2. Make it easy for a user to customize EDT emulation key bindings - without knowing much about Emacs Lisp; - - 3. Make it easy to switch between the original EDT default bindings - and the user's customized EDT bindings, without having to exit - Emacs. - - 4. Provide support for some TPU/EVE functions not supported in EDT. - - 5. Provide an easy way to restore ALL original Emacs key bindings, - just as they existed before the EDT emulation was first invoked. - - 6. Support GNU Emacs 19 and higher. (GNU Emacs 18 and below is no - longer supported.) XEmacs 19, and above, is also supported. - - 7. Supports highlighting of marked text within the EDT emulation on - all platforms on which Emacs supports highlighting of marked text. - - 8. Handle terminal configuration interactively for most terminal - configurations, when the emulation is invoked for the first time. - - 9. Support a PC AT keyboard under MS-DOS. - - -II. TERMINALS/KEYBOARDS SUPPORTED: - -Keyboards used under a Window System are supported via the edt-mapper function. -The first time you invoke the emulation under a window system, the edt-mapper -function is run automatically and the user is prompted to identify which keys -the emulation is to use for the standard keypad and function keys EDT expects -(e.g., PF1, PF2, KP0, KP1, F1, F2, etc.). This configuration is saved to disk -read each time the emulation is invoked. - -In character oriented connections not running a window manager, built-in -support for the following terminals/keyboards is provided: - - (1) DEC VT-100 series and higher. This includes well behaved VT clones and - emulators. If you are using a VT series terminal, be sure that the term - environment variable is set properly before invoking emacs. - - (2) PC AT keyboard under MS-DOS. - -Be sure to read the SPECIAL NOTES FOR SOME PLATFORMS sections to see if those -notes apply to you. - - -III. STARTING THE EDT EMULATION: - -Start up GNU Emacs and enter "M-x edt-emulation-on" to begin the emulation. -After initialization is complete, the following message will appear below the -status line informing you that the emulation has been enabled: - - Default EDT keymap active - -You can have the EDT Emulation start up automatically, each time you initiate -a GNU Emacs session, by adding the following line to your .emacs file: - - (add-hook term-setup-hook 'edt-emulation-on) - -A reference sheet is included (later on) listing the default EDT Emulation key -bindings. This sheet is also accessible on line from within Emacs by pressing -PF2, GOLD H, or HELP (when in the EDT Default Mode). - -It is easy to customize key bindings in the EDT Emulation. (See CUSTOMIZING -section, below.) Customizations are placed in a file called edt-user.el. (A -sample edt-user.el file can be found in the CUSTOMIZING section.) If -edt-user.el is found in your GNU Emacs load path during EDT Emulation -initialization, then the following message will appear below the status line -indicating that the emulation has been enabled, enhanced by your own -customizations: - - User EDT custom keymap active - -Once enabled, it is easy to switch back and forth between your customized EDT -Emulation key bindings and the default EDT Emulation key bindings. (See the -sample edt-user.el file below. Look at the binding to GOLD Z.) It is also -easy to turn off the emulation (via the command edt-emulation-off). Doing so -completely restores the original key bindings in effect just prior to invoking -the emulation. - -Emacs binds keys to ASCII control characters and so does the real EDT. Where -EDT key bindings and GNU Emacs key bindings conflict, the default GNU Emacs key -bindings are retained by the EDT emulation by default. If you are a diehard -EDT user you may not like this. The CUSTOMIZING section explains how to change -this so that the EDT bindings to ASCII control characters override the default -Emacs bindings. - - -IV. SPECIAL NOTES FOR SOME PLATFORMS: - - Sun Workstations running X: - - Some earlier Sun keyboards do not have arrow keys separate from the keypad - keys. It is difficult to emulate the full EDT keypad and still retain use - of the arrow keys on such keyboards. - - The Sun Type 5 and other more recent Sun keyboards, however, do have - separate arrow keys. This makes them candidates for setting up a - reasonable EDT keypad emulation. - - Depending upon the configuration of the version of X installed on your - system, you may find the default X keynames for the keypad keys don't - permit Emacs to interpret some or all the keypad keys as something other - than arrow keys, numeric keys, Home, PgUP, etc. Both Sun and HP have been - particularly guilty of making bizarre keysym assignments to the keypad - keys. - - In most cases, the X Windows command, xmodmap, can be used to correct the - problem. Here's a sample .xmodmaprc file which corrects this problem on - one Sun workstation configuration using an older SunOS release configured - with a Sun Type 5 keyboard: - - ! File: .xmodmaprc - ! - ! Set up Sun Type 5 keypad for use with the GNU Emacs EDT Emulation - ! - keycode 53 = KP_Divide - keycode 54 = KP_Multiply - keycode 57 = KP_Decimal - keycode 75 = KP_7 - keycode 76 = KP_8 - keycode 77 = KP_9 - keycode 78 = KP_Subtract - keycode 97 = KP_Enter - keycode 98 = KP_4 - keycode 99 = KP_5 - keycode 100 = KP_6 - keycode 101 = KP_0 - keycode 105 = F24 - keycode 119 = KP_1 - keycode 120 = KP_2 - keycode 121 = KP_3 - keycode 132 = KP_Add - - If edt-mapper.el does not recognize your keypad keys as unique keys, use - the command - - xmodmap -pke - - to get a listing of the actual key codes and the keysyms mapped to them - and then generate you own custom .xmodmaprc similar to the one above. - - Next, feed .xmodmaprc to the xmodmap command and all the Sun Type 5 keypad - keys will now be configurable for the emulation of an LK-201 keypad (less - the comma key). In this example, the line - - keycode 105 = F24 - - changes the X Windows name of the keypad NumLock key to be known - internally as the F24 key. Doing so permits it to be configured to behave - as the PF1 (Gold) key. - - The side effect of this change is that you will no longer have a NumLock - key. If you are using other software under X which requires a NumLock - key, then examine your keyboard and look for one you don't use and - redefine it to be the NumLock key. Basically, you need to clear the - NumLock key from being assigned as a modifier, assign it to the key of - your choice, and then add it back as a modifier. (See the "General Notes - on Using NumLock for the PF1 Key on a Unix System" section below for - further help on how to do this.) - - PC users running MS-DOS: - - By default, F1 is configured to emulate the PF1 (GOLD) key. But NumLock - can be used instead if you load a freeware TSR distributed with MS-Kermit, - call gold.com. This was once distributed in a file called gold22.zip and - came with the source code as well as a loadable binary image. (See - edt-pc.el in the Emacs lisp/emulation directory for more information.) - - PC users running GNU/Linux: - - The default X server configuration varies from distribution to - distribution and release to release of GNU/Linux. If your system fails to - recognize the keypad keys as distinct keys, change the NumLock state, - turning it on or off, as the case may be, then try again. If this doesn't - solve your problem, you may have to modify the X keysym mappings with - xmodmap. - - On one distribution on an Intel PC, the following .xmodmaprc set things up - nicely. - - ! File: .xmodmaprc - ! - ! Set up PC keypad under GNU/Linux for the GNU Emacs EDT Emulation - ! - clear mod2 - keycode 77 = F12 - keycode 96 = Num_Lock Pointer_EnableKeys - add mod2 = Num_Lock - - In this example, after feeding the file to the xmodmap command, the PC - NumLock keypad key will be configurable for the emulation of the PF1 key. - The PC keypad can now emulate an LK-201 keypad (less the comma key), the - standard keyboard supplied with DEC terminals VT-200 and above. This - .xmodmaprc file switches the role of the F12 and NumLock keys. It has - been tested on RedHat GNU/Linux 5.2. Other versions of GNU/Linux may - require different keycodes. (See the "General Notes on Using NumLock for - the PF1 Key on a Unix System" section below for further help on how to do - this.) - - NOTE: Remember, it may be necessary to have NumLock in one position (ON) - or the other (OFF) for the PC keypad to emulate the LK-201 keypad - properly. - - General Notes on Using NumLock for the PF1 Key on a Unix System: - - Making the physical NumLock key available for use in the EDT - Emulation requires some modification to the default X Window - settings. Since the keycode assignments vary from system to - system, some investigation is needed to see how to do this on - a particular system. - - You will need to look at the output generated by xmodmap invoked with the - "-pm" switch. examined. For example, on RedHat GNU/Linux 5.2 on a PC, we - get the following output when running xmodmap. - - "xmodmap -pm" yields: - - xmodmap: up to 2 keys per modifier, (keycodes in parentheses): - - shift Shift_L (0x32), Shift_R (0x3e) - lock Caps_Lock (0x42) - control Control_L (0x25), Control_R (0x6d) - mod1 Alt_L (0x40), Alt_R (0x71) - mod2 Num_Lock (0x4d) - mod3 - mod4 - mod5 Scroll_Lock (0x4e) - - - Note that Num_Lock is assigned to the modifier mod2. This is - what hides Num_Lock from being seen by Emacs. - - Now, "xmodmap -pke" yields: - - . - . - . - keycode 77 = Num_Lock Pointer_EnableKeys - . - . - . - keycode 96 = F12 - . - . - . - - So, in RedHat GNU/Linux 5.2 on a PC, Num_Lock generates keycode - 77. The following steps are taken: - - 1. clear the assignment of Num_Lock to mod2; - 2. swap the keycodes assigned to F12 and Num_Lock; - 3. assign Num_Lock back to mod2. - - The .xmodmaprc file looks like this: - - ! File: .xmodmaprc - ! - ! Set up PC keypad under GNU/Linux for the GNU Emacs EDT Emulation - ! - clear mod2 - keycode 77 = F12 - keycode 96 = Num_Lock Pointer_EnableKeys - add mod2 = Num_Lock - - So, after executing "xmodmap .xmodmaprc", a press of the physical - F12 key looks like a Num_Lock keypress to X. Also, a press of the - physical NumLock key looks like a press of the F12 key to X. - - Now, edt-mapper.el will see "f12" when the physical NumLock key - is pressed, allowing the NumLock key to be used as the EDT PF1 - (Gold) key. - -V. HOW DOES THIS EDT EMULATION DIFFER FROM REAL EDT?: - -In general, you will find that this emulation of EDT replicates most, but not -all, of EDT's most used Keypad Mode editing functions and behavior. It is not -perfect, but most EDT users who have tried the emulation agree that it is -quite good enough to make it easy for die-hard EDT users to move over to using -GNU Emacs. - -Here's a list of the most important differences between EDT and this GNU Emacs -EDT Emulation. The list is short but you must be aware of these differences -if you are to use the EDT Emulation effectively. - -1. Entering repeat counts works a little differently than in EDT. - - EDT allows users to enter a repeat count before entering a command that - accepts repeat counts. For example, when using the real EDT, pressing - these three keys in sequence, GOLD 5 KP1, will move the cursor in the - current direction 5 words. This does NOT work in Emacs! - - Emacs provides two ways to enter repeat counts and neither involves using - the GOLD key. First, repeat counts can be entered in Emacs by using the - ESC key. For example, pressing these keys in sequence, ESC 1 0 KP1, will - move the cursor in the current direction 10 words. Second, Emacs provides - another command called universal-argument that can be used to do the same - thing. Normally, in Emacs has this bound to C-u. - -2. EDT's line mode commands and nokeypad mode commands are NOT supported - (with one important exception; see item 8 in the Highlights section - below). Although, at first, this may seem like a big omission, the set of - built-in Emacs commands provides a much richer set of capabilities which - more than make up for this omission. - - To enter Emacs commands not bound to keys, you can press GOLD KP7 or the DO - key. Emacs will display its own command prompt "M-x". This stands for the - keypress Meta-x, where Meta is a special shift key. The Alt key is often - mapped to behave as a Meta key. So, you can also invoke this prompt by - pressing Meta-x. Typing the sequence "ESC x" will also invoke the prompt. - -3. Selected text is highlighted ONLY on systems where Emacs supports the - highlighting of text. - -4. Just like in TPU/EVE, the ENTER key is NOT used to terminate input when the - editor prompts you for input. The RETURN key is used, instead. (KP4 and - KP5 (the direction keys) do terminate input for the FIND command, just like - in EDT, however.) - - - - -VI. SOME HIGHLIGHTS IN THIS EDT EMULATION, AND SOME COMPARISONS TO THE - ORIGINAL GNU EMACS EDT EMULATION: - -1. The EDT define key command is supported (edt-define-key) and is bound to - C-k in the default EDT mode when EDT control sequence bindings are enabled - or one of the sample edt-user.el customization files is used. The TPU/EVE - learn command is supported but not bound to a key in the default EDT mode - but is bound in the sample edt-user.el file. - - Unlike the TPU/EVE learn command, which uses one key to begin the learn - sequence, C-l, and another command to remember the sequence, C-r, this - version of the learn command (edt-learn) serves as a toggle to both begin - and to remember the learn sequence. - - Many users who change the meaning of a key with the define key and the - learn commands, would like to be able to restore the original key binding - without having to quit and restart emacs. So a restore key command is - provided to do just that. When invoked, it prompts you to press the key - to which you wish the last replaced key definition restored. It is bound - to GOLD C-k in the default EDT mode when EDT control sequence bindings are - enabled or one of the sample edt-user.el customization files is used. - -2. Direction support is fully supported. - -3. All original Emacs bindings are fully restored when EDT emulation is turned - off. So, if a fellow worker comes over to your terminal to help you with a - software problem, for example, and is completely confused by your EDT - emulation bindings, just enter the command, edt-emulation-off, at the M-x - prompt and the original Emacs bindings will be restored. To resume the EDT - emulation, just enter edt-emulation-on. - -4. User custom EDT bindings are kept separate from the default EDT bindings. - One can toggle back and forth between the custom EDT bindings and default - EDT bindings. - -5. The Emacs functions in edt.el attempt to emulate, where practical, the - exact behavior of the corresponding EDT keypad mode commands. In a few - cases, the emulation is not exact, but we hope you will agree it is close - enough. In a very few cases, we chose to use the Emacs way of handling - things. As mentioned earlier, we do not emulate the EDT SUBS command. - Instead, we chose to use the Emacs query-replace function, which we find - to be easier to use. - -6. Emacs uses the regexp assigned to page-delimiter to determine what marks a - page break. This is normally "^\f", which causes the edt-page command to - ignore form feeds not located at the beginning of a line. To emulate the - EDT PAGE command exactly, page-delimiter is set to "\f" when EDT emulation - is turned on, and restored to "^\f" when EDT emulation is turned off. - But, since some users prefer the Emacs definition of a page break, or may - wish to preserve a customized definition of page break, one can override - the EDT definition by placing - - (setq edt-keep-current-page-delimiter t) - - in your .emacs file. Or, you can used the Emacs customize command - to change its setting. - -7. The EDT definition of a section of a terminal window is hardwired to be 16 - lines of its one-and-only 24-line window (the EDT SECT command bound to - KP8). That's two-thirds of the window at a time. Since Emacs, like - TPU/EVE, can handle multiple windows of sizes of other than 24 lines, the - definition of section used here has been modified to two-thirds of the - current window. (There is also an edt-scroll-window function which you - may prefer over the SECT emulation.) - -8. Cursor movement and deletion involving word entities is identical to EDT. - This, above all else, gives the die-hard EDT user a sense of being at - home. Also, an emulation of EDT's SET ENTITY WORD command is provided, - for those users who like to customize movement by a word at a time to - their own liking. - -9. EDT's FIND and FNDNXT are supported. - -10. EDT's APPEND, REPLACE, and SUBS commands are supported. - -11. CHNGCASE is supported. It works on individual characters or selected - text, if SELECT is active. In addition, two new commands are provided: - edt-lowercase and edt-uppercase. They work on individual WORDS or - selected text, if SELECT is active. - -12. Form feed and tab insert commands are supported. - -13. A new command, edt-duplicate-word, is provided. If you experiment with - it, you might find it to be surprisingly useful and may wonder how you - ever got along without it! It is assigned to C-j in the sample - edt-user.el customization files. - -14. TPU/EVE's Rectangular Cut and Paste functions (originally from the EVE-Plus - package) are supported. But unlike the TPU/EVE versions, these here - support both insert and overwrite modes. The seven rectangular functions - are bound to F7, F8, GOLD-F8, F9, GOLD-F9, F10, and GOLD-F10 in the - default EDT mode. - -15. The original EDT emulation package set up many default regular and GOLD - bindings. We tried to preserve most (but not all!) of these, so users of - the original emulation package will feel more at home. - - Nevertheless, there are still many GOLD key sequences which are not bound - to any functions. These are prime candidates to use for your own - customizations. - - Also, there are several commands in edt.el not bound to any key. So, you - will find it worthwhile to look through edt.el for functions you may wish - to add to your personal customized bindings. - -16. The VT200/VT300 series terminals steal the function keys F1 to F5 for - their own use. These do not generate signals which are sent to the host. - So, edt.el does not assign any default bindings to F1 through F5. - - In addition, our VT220 terminals generate an interrupt when the F6 key is - pressed (^C or ^Y, can't remember which) and not the character sequence - documented in the manual. So, binding emacs commands to F6 will not work - if your terminal behaves the same way. - -17. The VT220 terminal has no ESC, BS, nor LF keys, as does a VT100. So the - default EDT bindings adopt the standard DEC convention of having the F11, - F12, and F13 keys, on a VT200 series (and above) terminal, assigned to the - same EDT functions that are bound to ESC, BS, and LF on a VT100 terminal. - -18. Each user, through the use of a private edt-user.el file, can customize, - very easily, personal EDT emulation bindings. - -19. The EDT SELECT and RESET functions are supported. However, unlike EDT, - pressing RESET to cancel text selection does NOT reset the existing - setting of the current direction. - - We also provide a TPU/EVE like version of the single SELECT/RESET - function, called edt-toggle-select, which makes the EDT SELECT function - into a toggle on/off switch. That is, if selection is ON, pressing SELECT - again turns selection off (cancels selection). This function is used in - the sample edt-user.el customization files. - -20. EDT scroll margins are supported, but are disabled by default. (See - CUSTOMIZING section below for instructions on how to enable them.) - - -VII. CUSTOMIZING: - -Most EDT users, at one time or another, make some custom key bindings, or -use someone else's custom key bindings, which they come to depend upon just as -if they were built-in bindings. This EDT Emulation for GNU Emacs is designed -to make it easy to customize bindings. - -If you wish to customize the EDT Emulation to use some of your own key -bindings, you need to make a private version of edt-user.el in your own -private lisp directory. There are two sample files edt-user.el1 and -edt-user.el2 for you to use as templates and for ideas. Look at -edt-user.el1 first. Unless you will be using two or more very different -types of terminals on the same system, you need not look at edt-user.el2. - -First, you need to have your own private lisp directory, say ~/lisp, and -you should add it to the GNU Emacs load path. - -NOTE: A few sites have different load-path requirements, so the above - directions may need some modification if your site has such special - needs. - - -Creating your own edt-user.el file: - -A sample edt-user.el file is attached to the end of this user documentation. -You should use it as a guide to learn how you can customize EDT emulation -bindings to your own liking. Names used to identify the set of LK-201 -keypad and function keys are: - -Keypad Keys: - PF1 PF2 PF3 PF4 - KP7 KP8 KP9 KP- - KP4 KP5 KP6 KP, - KP1 KP2 KP3 - KP0 KPP KPE - -Arrow Keys: - LEFT RIGHT DOWN UP - -Function Keys: - F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 F13 F14 - HELP DO F17 F18 F19 F20 - - FIND INSERT REMOVE - SELECT PREVIOUS NEXT - -Note: - Many VT-200 terminals, and above, steal function keys F1 thru - F5 for terminal setup control and don't send anything to the - host if pressed. So customizing bindings to these keys may - not work for you. - -There are three basic functions that do the EDT emulation custom bindings: -edt-bind-key, edt-bind-gold-key, and edt-bind-function-key. - -The first two are for binding functions to keys which are standard across most -keyboards. This makes them keyboard independent, making it possible to define -these key bindings for all terminals in the file edt.el. - -The first, edt-bind-key, is used typically to bind emacs commands to -control keys, although some people use it to bind commands to other keys, as -well. (For example, some people use it to bind the VT200 seldom used -back-tick key (`) to the function "ESC-prefix" so it will behave like an ESC -key.) The second function, edt-bind-gold-key, is used to bind emacs commands -to gold key sequences involving alpha-numeric keys, special character keys, -and control keys. - -The third function, edt-bind-function-key, is terminal dependent and is defined -in a terminal specific file (see edt-vt100.el for example). It is used to bind -emacs commands to LK-201 function keys, to keypad keys, and to gold sequences -of those keys. - - -SPECIFYING WORD ENTITIES: - -The variable edt-word-entities is used to emulate EDT's SET ENTITY WORD -command. It contains a list of characters to be treated as words in -themselves. If the user does not define edt-word-entities in his/her .emacs -file, then it is set up with the EDT default containing only TAB. - -The characters are stored in the list by their numerical values, not as -strings. Emacs supports several ways to specify the numerical value of a -character. One method is to use the question mark: ?A means the numerical -value for A, ?/ means the numerical value for /, and so on. Several -unprintable characters have special representations: - - ?\b specifies BS, C-h - ?\t specifies TAB, C-i - ?\n specifies LFD, C-j - ?\v specifies VTAB, C-k - ?\f specifies FF, C-l - ?\r specifies CR, C-m - ?\e specifies ESC, C-[ - ?\\ specifies \ - -Here are some examples: - - (setq edt-word-entities '(?\t ?- ?/)) ;; Specifies TAB, - , and / - (setq edt-word-entities '(?\t) ;; Specifies TAB, the default - -You can also specify characters by their decimal ascii values: - - (setq edt-word-entities '(9 45 47)) ;; Specifies TAB, - , and / - - -ENABLING EDT CONTROL KEY SEQUENCE BINDINGS: - -Where EDT key bindings and GNU Emacs key bindings conflict, the default GNU -Emacs key bindings are retained by default. Some diehard EDT users may not -like this. So, if the variable edt-use-EDT-control-key-bindings is set to -true in a user's .emacs file, then the default EDT Emulation mode will enable -most of the original EDT control key sequence bindings. If you wish to do -this, add the following line to your .emacs file: - - (setq edt-use-EDT-control-key-bindings t) - - -SETTING SCROLL MARGINS: - -Scroll margins at the top and bottom of the window are now supported. (The -design was copied from tpu-extras.el.) By default, this feature is enabled -with the top margin set to 10% of the window and the bottom margin set to 15% -of the window. To change these settings, you can invoke the function -edt-set-scroll-margins in your .emacs file. For example, the following line - - (edt-set-scroll-margins "20%" "25%") - -sets the top margin to 20% of the window and the bottom margin to 25% of the -window. To disable this feature, set each margin to 0%. You can also invoke -edt-set-scroll-margins interactively while EDT Emulation is active to change -the settings for that session. - -NOTE: Another way to set the scroll margins is to use the Emacs customization -feature (not available in Emacs 19) to set the following two variables -directly: - - edt-top-scroll-margin and edt-bottom-scroll-margin - -Enter the Emacs `customize' command. First select the Editing group and then -select the Emulations group. Finally, select the Edt group and follow the -directions. - - DEFAULT EDT Keypad - - F7: Copy Rectangle +----------+----------+----------+----------+ - F8: Cut Rect Overstrike |Prev Line |Next Line |Bkwd Char |Frwd Char | - G-F8: Paste Rect Overstrike | (UP) | (DOWN) | (LEFT) | (RIGHT) | - F9: Cut Rect Insert |Window Top|Window Bot|Bkwd Sent |Frwd Sent | - G-F9: Paste Rect Insert +----------+----------+----------+----------+ - F10: Cut Rectangle -G-F10: Paste Rectangle - F11: ESC - F12: Beginning of Line +----------+----------+----------+----------+ -G-F12: Delete Other Windows | GOLD | HELP | FNDNXT | DEL L | - F13: Delete to Begin of Word | (PF1) | (PF2) | (PF3) | (PF4) | - HELP: Keypad Help |Mark Wisel|Desc Funct| FIND | UND L | -G-HELP: Emacs Help +----------+----------+----------+----------+ - DO: Execute extended command | PAGE | SECT | APPEND | DEL W | - C-g: Keyboard Quit | (7) | (8) | (9) | (-) | -G-C-g: Keyboard Quit |Ex Ext Cmd|Fill Regio| REPLACE | UND W | - C-h: Beginning of Line +----------+----------+----------+----------+ -G-C-h: Emacs Help | ADVANCE | BACKUP | CUT | DEL C | - C-i: Tab Insert | (4) | (5) | (6) | (,) | - C-j: Delete to Begin of Word | BOTTOM | TOP | Yank | UND C | - C-k: Define Key +----------+----------+----------+----------+ -G-C-k: Restore Key | WORD | EOL | CHAR | Next | - C-l: Form Feed Insert | (1) | (2) | (3) | Window | - C-n: Set Screen Width 80 | CHNGCASE | DEL EOL |Quoted Ins| ! - C-r: Isearch Backward +---------------------+----------+ (ENTER) | - C-s: Isearch Forward | LINE | SELECT | ! - C-t: Display the Time | (0) | (.) | Query | - C-u: Delete to Begin of Line | Open Line | RESET | Replace | - C-v: Redraw Display +---------------------+----------+----------+ - C-w: Set Screen Width 132 - C-z: Suspend Emacs +----------+----------+----------+ -G-C-\: Split Window | FNDNXT | Yank | CUT | - | (FIND) | (INSERT) | (REMOVE) | - G-b: Buffer Menu | FIND | | COPY | - G-c: Compile +----------+----------+----------+ - G-d: Delete Window |SELECT/RES|SECT BACKW|SECT FORWA| - G-e: Exit | (SELECT) |(PREVIOUS)| (NEXT) | - G-f: Find File | | | | - G-g: Find File Other Window +----------+----------+----------+ - G-h: Keypad Help - G-i: Insert File - G-k: Toggle Capitalization Word - G-l: Lowercase Word or Region - G-m: Save Some Buffers - G-n: Next Error - G-o: Switch to Next Window - G-q: Quit - G-r: Revert File - G-s: Save Buffer - G-u: Uppercase Word or Region - G-v: Find File Other Window - G-w: Write file - G-y: EDT Emulation OFF - G-z: Switch to User EDT Key Bindings - G-1: Delete Other Windows - G-2: Split Window - G-%: Go to Percentage - G- : Undo (GOLD Spacebar) - G-=: Go to Line - G-`: What line - G-/: Query-Replace - -;;; File: edt-user.el --- Sample User Customizations for the Enhanced -;;; EDT Keypad Mode Emulation -;;; -;;; For GNU Emacs 19 and Above -;;; -;; Copyright (C) 1986, 1992, 1993, 2000, 2001, 2002, 2003, 2004, 2005, -;; 2006, 2007, 2008, 2009 Free Software Foundation, Inc. - -;; Author: Kevin Gallagher -;; Maintainer: Kevin Gallagher -;; Keywords: emulations - -;; GNU Emacs is free software: you can redistribute it and/or modify -;; it under the terms of the GNU General Public License as published by -;; the Free Software Foundation, either version 3 of the License, or -;; (at your option) any later version. - -;; GNU Emacs is distributed in the hope that it will be useful, -;; but WITHOUT ANY WARRANTY; without even the implied warranty of -;; MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
