Okay, but you need special hardware (e.g. a converter) for that, to connect two keyboards to the same PS/2 keyboard port. (Also, this will just "merge" the input of all keyboards.)

Yes. With Bret's USB keyboard driver all the keyboard input will be "merged", but other drivers might only recognize the first keyboard. Windows' drivers probably "merge" two, but I don't remember whether I actually tried that.

Ah, so this trick was made an ad-hoc interface by people :-)

You would then have the option to run the modified program either with the one input method or the other, and switch between the two, right?
