IPAC4 shift key help needed.

[vetteguy112233]

I've set all of my keys in "unshifed mode", I want to set my COIN as Player 1 button / Player 1's button 5.

I also want to set ESCAPE as Player 1/ Player 2's button 5

I for some reason can't figure this out. I go into the SHIFTED KEYS, but do I need to select the "COIN" picture and then press P1 (which is the default shift key, right) and P1's B5 at the same time? Does it know that P1 is the shift button, so all I need to do is just press B5? I've tried all of this, but can't get the "COIN" icon to flash with when entering the keystrokes I want.

Hopefully this made sense, please help A.S.A.P.
