Solaris minus key not working

I have never been able to get the minus key to work on my Solaris SunBlade 2000, for any version of Blender that I can remember. If I try emulate numpad, my mouse no longer responds to clicks, in Blender, and other porgrams, although it seems OK for X (KDE) controls. It means that I can’t use proportional editing, maybe there is another key that does the same thing?

Thanks for any suggestions

If you have a mousewheel (and if solaris can use it) you can use it to alter the radius of the PET.

No mouse wheel just some sort of key board mapping problem. :-?
