making right alt key usable (was)Re: De-arrowing my system...how easy it is?)

[Linux for blind general discussion]

Greetings!


This discussion of keys prompts me to ask here how to get the use of my 
right alt key in the console, or especially using Emacs.  It seems to me 
I did this some years ago on a system that has gone to Linux Heaven, but 
I can't remember and have no record of how to do that.  I'd be grateful 
for any pointers.
