F4 is literally the most useless key on the keyboard. It's only used for ALT+F4! So make that useless F4 a shortcut for one of the most powerful key combos on your computer ever, ALT+F4, and avoid awkward hand manoeuvres while saving precious time!

This autohotkey script will mimic an ALT+F4 key press when you press F4. This is a great ALT+F4 alternative if you don't have any other use for your F4 key.

• For all user accounts: Drag and drop the .exe file onto Startup Folder (allusers) shortcut and re-log to your user account. This will effect all user accounts.
• For current user account only: Drag and drop the .exe file onto Startup Folder (user) shortcut and re-log to your user account. This will only effect your user account.

I only use XFCE as my desktop environment, so here's how you can do this on XFCE:

• Go to Settings Manager -> Window Manager

• Click on Keyboard Tab

• Find Close Window, change the shortcut to F4 and you are done. You don't need the autohotkey script from this repository.

• Systray icon is not hidden.
• May not work on some exclusive fullscreen applications(like 1%).
