Thank you again, really very kind! I downloaded the SetEdit app, I also changed some values to check if I understood (for example "pointer location").
But I didn't understand how I could use it for my purpose...
I apologize if you get bored, I am attaching the photo of the option that I would like to activate with Macrodroid.
Also, in the video "video_magnification" see how it works.
By enabling the gestures instead, you can see that in the video "video_with_gesture" the tutorial indicates to "swipe up with two fingers", but unfortunately it doesn't work.
Here: I would like to find an alternative with Macrodroid, to be activated with a button for example.
