Need to make my thumb buuton on my mouse do a Back

[Steven W. Orr]

I've looked everywhere and I can't find the answer. I'm hoping someone 
here might know how to do this.

Running Red Hat 9 and Mozilla 1.4b

I got my thumb button working as Button6 on my Logitech Cordless
Mouseman Wheel. Now I just need to know how to hook up the thumb
button to the Back function. Is there a way to do this key definition
for a mouse button under Mozilla?

Very grateful. TIA
