Disable open/close transition animation of T/N panels?

I’m noticing the transition effect now that I’m actually closing/opening these panels while I’m working. Is there a way to disable it so they open/close instantly? I’ve looked through the user prefs and nothing jumped out at me, and googling seems to yield results regarding video animation.

Nope. You have to press T/N to open or close them.

That wasn’t what I was asking. There’s a fading transition between open/close states rather than just popping in/out instantly. That’s what I was wondering about. I’m aware T/N is how you open/close them.

I see no fading. Don’t know why you do.

I got it. I guess it’s just something in the way Region Overlap works as it’s only doing it w/ that enabled.
