Here is a video for XClick + Image. Another option is to use the new XClickTextRelative. For this made a second video below.
XClick + Image
To create the image for XClick, use the “Select” button
Here we click relative to the word “Random”. The right value is found by testing. I started with 100,0 and see that this is too far way from the button. Then I try 10,0 and see it is too short. So I change to 40,0 and the click hits the button just right. To test the values, press the “Find” button.
