+;;; 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.
