The shiftbutton
If you ever've kids at your place you gonna love this feature! Regardless which combination of buttons you let perform as an Escape-function - kids will find them. Even worser when they find the configuration keys...
By the way - even my grownup-friends managed it to find some combinations by hacking wildy on any button they found during gameplay!
This button between the speakers is programmed as the "SHIFT"-key
of the I-Pac. When you just click on it,
the current game'll exit and you are back to the game menu. Holding it you can
press the fitting button on the
controlpanel to simulate TAB (game configuration), ENTER, Tilde(volume control)
and Pause of the current game.
