Is there anyone from the BTT community that answers questions like mine?
Is there some other way of getting Technical Support from BTT?

Does Mission Control also show up if you press fn+backspace (forward delete)? If so, does it also happen if BTT is quit?

Yes, anytime I push fn it goes to Mission Control, whether BTT is running or not. I'm going crazy trying to figure out why ... thank you.

Also, when BTT is running, Option-Delete brings up Mission Control. I don't know why!

You have probably accidentally enabled this in System Preferences => Mission Control.

BTT programmatically generating the forward delete key, might also press the FN key, thus maybe triggering your Mission Control.

That was exactly the problem! Thank you so much for your help!
