Quoting Ico
- I remap the numpad arrows to send 'Left' instead of KP_Left':
xmodmap -e "keycode 83 = Left Left" ...
- Xmonad now works with the keypad left arrow key, but the normal arrow key (that was not remapped) is no longer picked up by xmonad. It works for all other apps I tested, though. xev shows the normal key symbols when pressing the keys.
Yeah, that's a bit annoying. The culprit is that xmonad asks X to convert keysyms into keycodes, then binds keycodes instead of keysyms. This is subtly a bug because many keycodes may map to the same keysym, in which case X will choose one arbitrarily to return from the conversion. You might be interested in http://code.google.com/p/xmonad/issues/detail?id=273 which even has a patch you might want to try applying to xmonad core. Spencer is skeptical about the patch, but it looks like just what the doctor ordered to me. ~d
