Thanks, it works by changing the frontend.key.escape to 
frontend.key['escape'] and so forth.  I had added the sleeps whilst 
trying to get it to work, thinking it may be ignoring to many commands 
to quickly.  Had not thought of try the keys directly. I thought that at 
some point checking the return values from frontend.key.escape and 
receiving True, using "print frontend.key.escape" is returning False for 
me now.

(The last step in my frontend idle script):
Any idea whether I can query the frontend to see if it is playing music 
/ video via AirTunes / AirVideo?  A query location returns the frontends 
location (obviously), butI dont see any way to query exactly what the 
frontend is doing.   Would be nice to be able to query in more detail 
what the frontend is doing..
