The best way to do this in Morphic is with "alarms":

    self addAlarm: #changeKeyboardFocus after: 5000.

which would execute the morph's changeKeyboardFocus method 5 seconds later.

The way of sleeping you suggest is possible too but more tricky, since you
would have to move your wait code to an extra process to not block the UI
process, but then make sure that the actual work is done in the UI process
again (Morphic is not multithreaded, although Squeak is).
