// GrabChecked grabs a button with mods on a particular window. It does the

// on failure.

// If 'sync' is True, then no further events can be processed until the
// grabbing client allows them to be. (Which is done via AllowEvents. Thus,
// if sync is True, you *must* make some call to AllowEvents at some
// point, or else your client will lock.)
