@vindex uniquify-buffer-name-style
There are several styles to make buffer names unique. To select
some other programs. Emacs does not require any of these environment
variables to be set, but it uses their values if they are set.
-@table @env
+@vtable @env
@item CDPATH
Used by the @code{cd} command to search for the directory you specify,
when you specify a relative directory name.
@code{load-path} variable (@pxref{Lisp Libraries}). An empty element
stands for the default value of @code{load-path}; e.g., using
@samp{EMACSLOADPATH="/tmp:"} adds @file{/tmp} to the front of
-the default @code{load-path}.

+middle of the list, use 2 colons in a row, as in
+@samp{EMACSLOADPATH="/tmp::/foo"}.
@item EMACSPATH
A colon-separated list of directories to search for executable files.
If set, Emacs uses this in addition to @env{PATH} (see below) when
@item VERSION_CONTROL
Used to initialize the @code{version-control} variable (@pxref{Backup

It is not advisable to put anything in @file{site-load.el} or
@file{site-init.el} that would alter any of the features that users
expect in an ordinary unmodified Emacs. If you feel you must override

+@defun register-read-with-preview prompt
+@cindex register preview
+This function reads and returns a register name, prompting with
+@var{prompt} and possibly showing a preview of the existing registers
+and their contents. The preview is shown in a temporary window, after
+the delay specified by the user option @code{register-preview-delay},
+if its value and @code{register-alist} are both non-@code{nil}. The
+preview is also shown if the user requests help (e.g., by typing the
+help character). We recommend that all interactive commands which
+read register names use this function.
