I don't think this capabilility currently exists in Alice
- at least the question has been asked multiple time and I haven't seen any response.
It may be possible to write a simple script to simulate the needed keyboard inputs (hold the mouse over the buttons on the screen that the world plays in to see the keystroke equivalents) but so far this has exceeded my programming capabilities
and may not be part of the implemented functions. (See the first reference and general comments in this forum on the status of Alice scripting - it was in 1.0 but apparently not fully implemented in 2.0.)
Anyway, the references I'm starting with are:
http://www.westga.edu/~drocco/alice/scripting.html
http://www.rutherfurd.net/python/sendkeys/#overview and

Please post the results if you have any success -
or if you see an obvious flaw in this line of thought.
This would really be something nice to have.
