37 ** If you set find-file-confirm-nonexistent-file to t, then C-x C-f
38 requires confirmation before opening a non-existent file.
39
40 ** If the gpm mouse server is running and t-mouse-mode enabled, Emacs uses a
41 Unix socket in a GNU/Linux console to talk to server, rather than faking events
42 using the client program mev. This C level approach provides mouse
43 highlighting, and help echoing in the minibuffer.
44
45 ** The new variable next-error-recenter specifies how next-error should
46 recenter the visited source file. Its value can be a number (for example,
47 0 for top line, -1 for bottom line), or nil for no recentering.
