From 3b8d3d379b2778cfdbc2c1e1c6c448303311e20f Mon Sep 17 00:00:00 2001

Subject: * input.h (cook_keycode): added prototype

* actions.c: key_actions now uses the #define'd keysyms from X11/keysym.h

* events.c (handle_key): calls cook_keycode() before processing the keysym.

* input.c (read_key): calls cook_keycode() before returning the keysym
(cook_keycode): added.
