Hi,

Can you be more precise on what is not working? Does it work with a mouse? Does the stylus work in other applications? Is there any specific website for which this addon is not working?

Unfortunately many shortcuts are already taken by browsers and are not overridable, as far as I know, CTRL-X was a way to keep controls on the bottom row of the keyboard without stretching your hand each time. If you have any better alternative, I would happy to add it if possible.
