Send physical click on window element
The attached Process, sends a mouse click to a notepad element, using the "Location and Size" attribute of the element.
This means that regardless of the position of the window and the screen resolution, the click will always be sent to the right place.
Feel free to modify the first two (2) Actions accordingly, in order to send a click to your desired element.
The alternative to the above is the "Click Element in Window" Action, which is much simpler. However, it is always good to have alternatives :)
