A sample edt-user.el file is provided in the Emacs etc/ directory. 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> through <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
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.
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
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.
