FastTap Property
Qubes 6.5 Used to support fast tapping on buttons, introduced in Qubes 6.5.
By default, buttons respond to tapping actions on touch-screen interfaces with a lag of approximately 300 ms. This lag is necessary to differentiate between a click on a button and a finger touch like page scrolling, or more complex gestures involving multiple fingers.
When the FastTap option is set to True, there is no lag, and the slightest brush of a finger will immediately be considered as a click.
