I believe when editing the action filter (step 4) you want the 'Run action on' set to 'Select'.
However this will be a single click for navigation. Not a double click.
Cor - Yes, that's what I currently have. However, I want the user to be able to click anywhere in the particular area, as opposed to clicking on a specific textbox.
Hmm. Well, it's based off of the mark. You could make the mark a square and increase the size so that it filled up the entire area.
Just click on 'Size' in the marks card and move the slider to the right until the squad fills up the entire space.
