OT: key mapping on Windows

[Jeroen Elias]

Hello,

I know this is off-topic, but I remember people on this list have some 
pretty good ideas.

I am looking for a program which can map keyboard strokes to other key 
strokes
on a Windows system, something like Ctrl-J mapping to Ctrl-G.
I know a few programs which can do that "system-wide", meaning the mapping
works on every program running.
What I would like to have is a "per-program" key mapper.

Say, for instance, program A expects Ctrl-G to jump to a specific line 
(like Notepad) and
another program B expects Ctrl-J to jump to a specific line.

Does anyone know a keymapper which can do this?

Any help very much appreciated (and sorry for my bad English :-) )

Regards,

Jeroen Elias
