Key mapping in X.org

[Josh Paetzel]

I'm trying to set up a keybinding in X.  I would like Right Shift + 
Enter to be treated the same way that Enter is when pressed alone.  
Right now pressing Right Shift + Enter doesn't appear to do anything 
at all. 

I've read through the xset and stty man pages and didn't spot what I 
need.  

A nudge in the right direction would be most appreciated.
