ungrab-keyboard-before-action

Browse Source 
If an action that requires the keyboard to be grabbed (e.g., launching dmenu),
it is a race when submapping the action as to whether the action will have
access to the keyboard or not. To fix this, the keyboard should be ungrabbed
before executing the action.
