As of r21811, there is now a "Set" button to start listening for keys, or one can double-click into the shortcut edit field to do the same.

The "find shortcut" still has the same problem but since it's the last control in the tab order, it's hopefully less problematic.

@a11cf0 do you want to test-drive this?

I've just tested this change. The idea is really great, but there is one noticeable bug. After pressing a key, the shortcut entry box gets properly disabled, but it's still not possible to get the focus out of it, as it gets stuck.

Please check out r21814, focus should now move back to the Set button.

Perfect. Many thanks for this improvement.
