how can I print a list of triggers for each app (or even better: display a menu of gestures/triggers)

Hello, my IQ is in the lower normal range. I keep forgetting my gestures. Is there a way to print the list of gesture / triggers for each app ?
Or even better, is there any way to display a menu of app specific gestures / triggers while I am working in an app ?
I know that I can open BTT and just do a screenshot but the result is not great.
thank you
