Search for "Mouse Mode" and you will find that it does have built-in mouse control that only works with a Philips or All4One IR keyboard which is no longer available.

Other folks have approached this by learning 4 directions from an IR mouse. Then, simply provide a 4-way cursor on the pronto screen and voila, you have a mouse. However, you should realize that doing complex actions like Shift-Mouse Drag, Alt-Left-Click, etc require advanced knowledge of IR protocols and are not easily done by the uninformed user.
