Laptops :: mouse wont click-how to map a keyboard key?

Well, after a number of reinstalls, installing GPM, and XFREE86, my mouse buttons still will not click.
Im getting tired of wrestling with these buttons and plan on getting a new mouse , but until then I would like to get my X browser functional. Is there anyway I could map a keyboard key to act as a mouse click? Because the mouse moves but the buttons will not click no matter what I do.
Any suggestions would be really appreciated.

Thanks,
Kyle
