I hide most admin functions somewhere else (inside the coin door, on the bottom of the control panel, on top of the cabinet).
My CP only has pause/select and exit, and then I have shifted functions thanks to the ipac. The top of my cab has a shutdown button that is also TAB, and shifts to SERVICE. Inside the coin door I have TEST, Speed up (for skipping through rom checks, etc). I have the player 2 coin reject rigged up with a microswitch so I can press it for credits.
