;;; AT&T UnixPC keyboard definitions
;;; Brant Cheikes (brant@linc.cis.upenn.edu, manta!brant)
;;; 4 August 1987
;;;
;;; Tested on: GNU Emacs 18.47.1 of Fri Jul 24 1987 on manta (usg-unix-v)
;;;
;;; The AT&T Unix PC (aka PC7300, 3B1) has a bizarre keyboard with
;;; lots of interestingly labeled function keys.  This file tries to
;;; assign useful actions to the function keys.  Note that the Shift
;;; and Ctrl keys have the same effect on function keys, so Shift-F1
;;; is the same as Ctrl-F1.
;;;
;;; Most of the information needed to create this file was taken from
;;; documentation found in lisp/keypad.el
;;;
;;; Bug: The "Beg" and "End" (unshifted) keys are not supported because
;;; they generate <esc>9 and <esc>0 respectively, and I know not how to
;;; deal with them.

(require 'keypad)

;;; There seem to be three prefixes for AT&T UnixPC function keys:
;;; "<esc>O", "<esc>N", and "<esc>[".  There seem to be a couple
;;; keys that just generate "<esc><digit>".
;;;
;;; Note: for each mapping, I indicate the key on the Unix PC followed
;;; by the Emacs command it is bound to (if any).  Note that when I
;;; couldn't figure out anything useful to do with a key, I simply bound
;;; it to 'previous-line, arbitrarily.  My goal was to get keys to do
;;; "mnemonic" things.
