i am not a touch screen expert but are there touch interface apps you can use that map your taps as needed to suit apps such as edge
e.g. for my physical remotes, I use a program called intelliremote that intercepts and maps remotes' key presses, replacing them with specific keyboard/mouse etc actions, and that can also be set to change its mapping depending what program is in focus at the time

google touch screen gesture mapping
