Wait suspends command processing for the given number of wait_frames or, when no argument is supplied, until all model movement has ceased. In the latter case, if a command such as roll has been activated for a given number of frames, the command following the wait command will not be executed until the roll is completed.
The wait may be interrupted by pressing the Esc key. This breaks out of wait but does not freeze the screen (i.e., any active motion continues until completion).
