Shortcutd: auto-focus command
 

I have troubles with my camera key, focus function works with soft press no more (can still focus with Live Focus app), so I wonder if I could use the proximity sensor for it. Shortcutd make it possible to use custom shell command. But I have no idea, what the command for auto-focus is. Has anyone more info about this question? Thanks a lot for help.

Update: have n900
