New BTT user, wanted to set up three-finger pinch to send ctrl-W (close tab) \and three-finger spread to send cmd-shift-T (reopen closed tab) to Chrome and Firefox. It seemed simple enough, but I can't seem to get it to do anything. I tried setting the gesture to trigger a HUD display and didn't get that either.
I'm pretty sure I'm missing something obvious, but is there any way to "debug" your gestures?
