;;; Commentary:

;; This file is loaded by x-win.el at run-time when we are sure that XEmacs
;; is running on the display of something running XFree86 (Linux,
;; NetBSD, FreeBSD, and perhaps other Intel Unixen).

;;; #### bleck!!! Use key-translation-map!

;;; #### Counter-bleck!! We shouldn't override a user binding for F13.
;;; So we use function-key-map for now.
;;; When we've implemented a fallback-style equivalent of
;;; keyboard-translate-table, we'll use that instead. (martin)

;; For no obvious reason, shift-F1 is called F13, although Meta-F1 and
;; Control-F1 have normal names.

  ;; We know this keyboard is an XFree86 keyboard. As such, we can predict
  ;; what key scan codes will correspond to the keys on US keyboard layout,
  ;; and we can use that information to fall back to the US layout when
  ;; looking up commands that would otherwise fail. (Cf. the hard-coding of
  ;; this information in /usr/X11R6/lib/X11/xkb/keycodes/xfree86 )
  ;;
  ;; These settings for x-us-keymap-first-keycode and
  ;; x-us-keymap-description were determined with
  ;;
  ;; setxkbmap us
  ;; xmodmap -pke > keyboard-description.txt
  ;;
  ;; "8" is the key code of the first line, x-us-keymap-description is
  ;; taken from the column describing the bindings.
