I'm using a Windows application in Crossover in which I've found it most convenient to assign my Mac keyboard's Command key – which gets translated into the Alt key when running this Windows application in Crossover – plus the function keys F1-F12. If I hit Alt-F4, the application quits. This is normal Windows behavior. I'd like to be able to use Alt-F4 as a keybind in this application but to do so the normal Windows Alt-F4 behavior of immediately quitting out of the application needs to be disabled.

I know I can use System Preferences to assign my keyboard's Command key to generate a different modifier keypress. I also know that I can use a different keybind in my application other than Alt-Whatever. I am currently doing the latter and it's a tolerable workaround. However, I would prefer to use my keyboard Command key without having to assign it a different keypress before using this app (and then setting it back to its default when done using this app) and would like to use the keybinds I prefer of Alt-F1 through Alt-F12 rather than Shift-F1 through Shift-F12 which is what I am using now in order to avoid this problem.

Is it possible to disable the normal Windows Alt-F4 behavior of immediately quitting out of the application so that Alt-F4 can be bound to a function within this Windows application?

I received a reply from Codeweavers technical support. The reply did not directly address my question but did offer workarounds – workarounds I was already using. There does not seem to be a way to disable the usual Windows behavior of Alt-F4 causing an immediate shutdown of the focus application and therefore such a keybind within a Windows application must be avoided.
