Yes but that is a very limited third button. You cannot do chording (e.g. left+middle buttons together) using that approach. Some specialized applications use chording.
Edit: spelling because phone.

Just curious, which popular app use that?
Isn't pushing 2 buttons at the same time on a 2-button mouse the same as pushing the third button on a 3 button mouse?
