Was going to say:
Power takes you "bacK" in menu's. On root of the menu, it will turn on/off screen. Hit Power again to turn it back on.
Vol+/Vol- lets you scroll up/down through menus
Pushing optical trackpad in makes your selection

1) Place your app you want to install into the root of your sd card (this is easiest)
2) Go into Clockworkmod Recovery (Explained in 7)
3) Mount system and sdcard under partitions (Explained in 7)
4) Connect Phone to PC
4a) adb remount in command prompt (should sow successful) (again, in 7)
5) Open Adb Shell on your PC
6)
IF NOT at #, type "su" to go from $ to #.
Type:
/system/bin/mv /sdcard/Your_App_Name.apk /system/app/Your_App_Name.apk
7) If you don't get errors, you're done. You can unplug phone, and reboot
