T42 button configurarion

[Guest]

I have a new T42 - first IBM notebook. I like all the configuration possibilities with the pointing devices. One thing I would like to do and can't seem to find a way to do - change the Track Point buttons so that I can do other things with them - such as browser back and so forth. I see I can those things with the Tapping Zones but would love to be able to set up a free button that way. Any possibility? Thanks in advance for any info.
