Is XKB universally available? AFAICT, we don't require it, but use it if available (not for XkbTranslateKeyCode, though). > However, in Elisp this is further complicated by there being no > real KeyEvent structure, instead it's a single integer as far as I > can see. Why would you need that? If we decide to use XkbTranslateKeyCode, we could translate the keycode in C, according to some logic that took into account the modifiers and perhaps also some user options, and returned the resulting translated character.
