Help With Flash Development For Psp

i was wondering what buttons do what on the psp

for example could someone tell me what the x button is on the pc so that i know what i am doing when i code, i would update to find out but i don't have wireless internet to make flash available.

THANKS IN ADVANCED

Up, down, left, and right are obviously... up, down, left, and right.
Anlog is mouse pointer. X seems to mouse click.. thats all i know :)

ok thanks
