Norton - OK to use Alt-F4 instead of clicking the x?

I hope this isn't too stupid a question, :smileywink: but something I've always wondered about, with Norton Internet Security, is whether or not it's okay to use a keyboard shortcut (Alt-F4) to close the Norton user-interface, instead of having to click the "x" in the corner. I prefer keyboard shortcuts wherever possible.

But I don't want to somehow inadvertently shut down more of Norton than I'd intended :smileysad: - I want to keep all of the protection stuff going; I just want to close the user-interface. Does Alt-F4 shut down too much of Norton, or is it exactly the same as clicking the "x"?

It's my understanding (please correct me if I'm wrong) that Alt-F4 is the same thing as using an app's "File" menu and then selecting "Exit" (or hitting Alt-F-X), but since Norton doesn't have a File menu, I've been unsure about using the alternative method of Alt-F4 with Norton.

So is it okay to use Alt-F4 to close Norton (like after I've done a manual scan or whatever), or should I just continue to play it safe and click the "x" in the corner instead?
