UPDD commander is highly configurable with All Applications defining the default set of system wide gestures and actions with individual applications / group use to specify gesture / action sets appropriate to their requirements.
In addition to the above you can have separate gestures also associated with defined UI elements (areas) utilised within the applications.
With this high degree of gesture configurability it can sometimes be confusing if a performed gesture does not do as expected, and it is sometimes useful to analyse the gesture processing being undertaken by Commander.
To this end the setting dialog function bar offers an option to show the application selection process based on the next performed gesture on the touch screen:
Select this option and perform the gesture. Commander will then reveal the selected target for the gesture, as in this example performing a One Finger Press on the Desktop (a UI element within the Finder Application)
If the gesture is performed on an application that is currently hidden in the Application List you will see this dialog:
You will need to 'Show and Select Gesture' to see the result of the application selection.
If the gesture performed is not defined, the highlighted 'Select next performed gesture' will stay highlighted, indicating this gesture will not be actioned.
This can occur, for example, if you perform a gesture within an application that is defined within the application list but does not contain a gesture definition of the gesture performed.
