There is a slight difference, but almost not worth mentioning. Using your example, let's say I set MAME up using a keyboard so TAB is "P and L Ctrl". On the I-PAC (without changing MAME) pressing the key combination will bring up the TAB menu. On the keyboard, pressing the key combination will either pause the game, activate P1B1, or both, and THEN bring up the TAB command. Not that it would make much difference in most games.
