Is it possible to map mouse clicks to a keyboard in RHEL4? Specifically I'm looking to map the Ins, Home, and PageUp keys as left, middle and right mouse buttons. Odd request I know, but all the xmodmap documentation I've read seems to indicate that it is not possible.

I can say that I have never heard of that. I would assume that handicap access type of solutions would or may exist to get you close. The internals of the x86 computer I think I remember do not allow a direct link as such even though they are on the same chip if ps/2. I am sure that other computer designs would support that more directly. The x86 differs from the mainframe in that things are hardwired from the start where big boxes are more device only in software. I guess you could write a usb program to capture that if both were usb. Might work with just a usb mouse. You'd have to capture the click (via an app) and translate it to the keyboard via a out of my league programming. I tried to make a touch screen input driver for an old OS and it took me a year to find out I wasn't smart enough to reverse the OS. Linux doesn't have that problem since is is open (but not fully documented). I read it wrong and answer it wrong too. So get off my case you goober.
