Panthercules, do this:
1) Download and install SetKeys 1.11 for SH3, it's in the download section here at subsim.
2) Make a
copy of your commands.cfg file somewhere else on your drive. That is
important, you don't want to edit your
real commands.cfg with SetKeys as there are some keys it will break in SH4 (it was written for SH3...)
3) Point SetKeys to the copy you made. Locate the commands you want and assign keys to them, then save the file.
4) Open up your edited copy in Notepad or your favorite editor, and open the
real commands.cfg in another session of your editor.
5) Locate and copy/paste the commands you changed in the copied/edited commands.cfg into the real commands.cfg. Then save and enjoy!
Of course, back up your live commands.cfg 1st in case something goes wrong
I've done a number of keymappings this way and it works great!
HTH!
