📝 Walkthrough

Walkthrough

This PR adds support for the ALT+ENTER key binding in the input control system. The Binding enum gains a new ALT_ENTER constant that is formatted as "ALT + ENTER" and classified as an extra binding. The input event handler explicitly implements the key press/release sequence for this binding via xServer.

Looks good to me.

Are there any other potential combinations we may want?

Thanks! There aren't any other combinations that I can think of that would be useful here. But we are missing END, INSERT, = and `/~ keys from the action list too. Should I go ahead and add those as well? Tilde is often used as the developer console for valve games.
