Yes What he said..
At least for those of us that don't have fancy encoders to
do the work for you...

I was already looking at other key remapping tools....
though I did not want to actually be force to permanently change
the keys if I can avoid it!
I really just need to get rid of any locks windows XP has on these
keys!
I have most of my emulators set up nicely and they use the Left Alt
keys; so changing it permanently would make me have to remap
a ton of emulators...

Most emulators are fine its just the ones that dont lock
out the Windows XP keys that are troublesome.
PSX emulator is the #1 culprit but a few others as well.
