The two Actions used in this case are:
- Transport: Play/pause - pauses the play cursor at the current position
- Transport: Play/stop - puts the play cursor back to the starting position (at the edit cursor)
You can assign or change the shortcuts to these Actions in the Action List.
As example: if you want both Enter and Space to pause the play cursor at the current position - assign both keys to the
Transport: Play/pause Action.
