I use the action in canvas A jump to a canvas B. In canvas B, I want to use the action to jump the last canvas, now is A.
You can jump to the previous canvas using actions. What you’d do is select a graphic on Canvas B, and choose “Jump to” and pick “Switch to previous canvas” from the dropdown. You can also select Switch to a specific canvas if you want to jump to a specific canvas rather than just the previous one. I’m not entirely sure that I understood your question, but hopefully this gives you a few things to try.
