How do I Trigger an Action with a single tap?

I want to summon the cheat sheet by double clicking the menu bar, which is a Trigger in itself, even though I’m double-tapping with a Force Trackpad. To hide the cheat sheet I will move the cursor over it and tap. But I cannot find a trigger to do this. I had the idea to setup in “Normal Mouse Buttons” as it offers a Left-click trigger where the condition is “hover_state” over the cheat sheet window, but it didn’t work.
Any idea how to do this?
