Last change on this file since fa09449 was fa09449, checked in by Jiri Svoboda <jirik.svoboda@…>, 16 years ago

Keycodes, keyboard events, kbd_event_get(). Keyboard driver now (formally) produces kbd events (press/release, keycode, mods, char) instead of just characters. In reality, the driver and client are only hacked to work with the new interface atm.
