F11 key

[graziano]

Can the F11 key functionality in IE be enabled by a php script
(pressing one full window , pressing two , returns to original size) ?

Thanks

Its enabled by default anyways, or always has been whenever I've tried it.

But PHP is server-side, to enable\disable things like that you need a client-side language, like JavaScript that does things 'live' without you having to hit a submit button.
