Have not seen double click for navigation on any FMP database or application that contains buttons. That I remember.
It is common to create invisible buttons for navigation.
Double tapping a spot on the screen in Fm GO an be detected using the OnGestureTap trigger. This does not work in FileMaker Pro.
Trying to set up a button that can be double clicked is not worth the effort, IMO, though it is possible if you track the timestamp of each time the button is clicked. (If the interval between 1 button click and another is 1 second or less, you have a double click.)
What is pretty easy to do is use Get ( ActiveModifierKeys ) to detect that a particular modifier key such as ctrl, shift, caps lock, alt, command or option is down and thus, for example, do something different if the shift key is held down while clicking the button.
