ubuntu linux -- mouse scroll wheel up or down to type letters?

Question

Is it possible to have the scroll wheel on my mouse send a keystroke instead? so when i scroll upward it sends the letter "a" and downward it sends the letter "b"?

Answer 1

You'd have to have a daemon in place that would catch the mouse scroll via the event subsystem and inject the keypress via uinput. I don't know of a daemon that does this.
