Hmm….. What about forcing a key action? If on click, I can replicate the pressing of F11, then it’ll make the browser full screen, and then when clicking the close button, it forces F11 again moving it back to whatever size the user had it.
Is that possible? I’m not sure because forcing a keystroke sounds like it could be misused by a lot of people if they chain it into a series of forced keystrokes. Anyone have an opinion?
