IBM optical Navigator mouse, how many buttons?

[gingo]

How many extra buttons does the IBM Optical Navigator have?

In the pictures I've seen it looks like one extra button on the left side. Is that all? Can that button be programed to do anything you want? 1 extra button is fine, but I want at least one. I gotta have that extra button for fast reloads while playin fps's.

It has four buttons including the scroll wheel and the documentation suggests you can remap the buttons with the drivers.

Yes the scrool mouse button and the button on the left side can be programed to do other stuff. Thats all the extra buttons there are. Oh by the way, MOHAA does not regonise the button on the side. (halflife does though)
