Oh. I would like every emulator to close with 'escape.'

Clicking File and then clicking Exit is an alternate way to exit the emulator.  Or Ctrl Alt and Delete and closing the emulator from the menu is another way.  Alt-F4 is universal way to close any program on a window machine. Ctrl-C will close a dos game like Day of the Tentacle.

Don't feel bad, I've been using Windows for 25 years and this is the first I've heard of Alt-F4. 😄 Many applications I've used, Ctrl-Q quits. Esc works to quit most of the versions of MAME I've used. However, in Fusion it toggles full-screen mode.
