Grab the keyboard

Actively grabs control of the keyboard and generates FocusIn and FocusOut events. Further key events are reported only to the grabbing client.

Any active keyboard grab by this client is overridden. If the keyboard is actively grabbed by some other client, AlreadyGrabbed is returned. If grab_window is not viewable, GrabNotViewable is returned. If the keyboard is frozen by an active grab of another client, GrabFrozen is returned. If the specified time is earlier than the last-keyboard-grab time or later than the current X server time, GrabInvalidTime is returned. Otherwise, the last-keyboard-grab time is set to the specified time.
