Fullscreen?

How can I make my game to appear full screen (or is it even possible?) or when I click a key thanks in advance ;)

Click the "Properties" in the left tab and tick the "Fullscreen" box.

or on a click

1:Right click on the layout - Insert new object - Mouse&Keyboard

2:In the "Event Sheet Editor" - RMB - Insert event - M&K - On key pressed - select the key - finish

3:To the event - +New action - System - Set fullscreen - select mode

Thanks! ;)
