From: Steven Tamm Date: Fri, 11 Nov 2005 16:33:44 +0000 (+0000) Subject: macterm.c (backtranslate_modified_keycode): New function to X-Git-Tag: emacs-pretest-22.0.90~5949 X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=b02e3f7ba66a48d30c8ebd5be03ff75c156564b0;p=emacs.git macterm.c (backtranslate_modified_keycode): New function to mask modifiers off of keycodes for use in modifier mapping. (mac_determine_quit_char_modifiers): Remove mac-reverse-ctrl-meta and replace it with more flexible system mapping mac modifier keys to emacs modifier keys. (convert_fn_keycode): Map Fn-keys to their original keycode using a table (english keyboard only). (syms_of_macterm): Define mac-control-modifier, mac-command-modifier, mac-function-modifier. Define meta and ctrl for use as modifiers. --- diff --git a/src/ChangeLog b/src/ChangeLog index 80df9d42123..7fab16badf7 100644 --- a/src/ChangeLog +++ b/src/ChangeLog @@ -1,3 +1,16 @@ +2005-11-11 David Reitter + + * macterm.c (backtranslate_modified_keycode): New function to + mask modifiers off of keycodes for use in modifier mapping. + (mac_determine_quit_char_modifiers): Remove + mac-reverse-ctrl-meta and replace it with more flexible system + mapping mac modifier keys to emacs modifier keys. + (convert_fn_keycode): Map Fn-keys to their original keycode + using a table (english keyboard only). + (syms_of_macterm): Define mac-control-modifier, + mac-command-modifier, mac-function-modifier. + Define meta and ctrl for use as modifiers. + 2005-11-11 Kim F.
