mapping mouse button 8 to Ctrl+2

[Hugo Vanwoerkom <hvw59601@care2.com>]

Hi,

I have a simple task:

when I hit mouse button 8 I want it to simulate a Ctrl+2 key.

I looked at xvkbd and that keeps a keyboard hanging around, I want this 
thing in the background always doing that mapping.

Then xbindkeys seemed to be good, but it seems to want to execute 
commands only and Ctrl+2 is no command, just a key stroke.

Anyone have a solution?

Thanks!
