Is that in the overview or outside? There are basically two input modes
- "normal" and "shell". The former uses X events directly and only works
if no global keyboard grab is in place; the latter uses Clutter events
and only works while the shell has grabbed the keyboard.

Keybindings should be defined using global.display.add_keybinding() -
the problem with that is that those keybindings won't work in the
overview (see _globalKeyPressHandler() in main.js for what we do to make
some keybindings available there). A second key press handler like the
one you are using can be used to work around that for now, but we should
probably add some allow_keybinding_in_overview() API for that case ...
