I've programmed a GUI in Python using the pythondialog package (which in turn relies on curses). One of the standard menu screens (fselect) requires the user to hit the space-bar in order to select a file from a file browser. Obviously, this is not directly possible with the RPi 7" touch screen (or any other touch screen for that matter). Is it possible to configure a certain gesture to emulate the space-bar e.g. double-tap?
