How do you get around Apple's modifiers from multiple keyboards limitation?

[David Rogoff]

Hi Takayama!

I've been using your great program and love it and really appreciate your work and support!  I have a question: I was looking at adding a programmable keypad alongside my keyboard.  I wanted to use opt/cmd/ctrl/shift to have it generate different codes.  However, a tech from the company reminded me of Apple's (dumb, in my opinion) restriction that doesn't allow modifier keys from one keyboard to affect keys on a different keyboard.  When I went to look into a program that is supposed to get around this, I was very surprised to find out that my Mac didn't have this limitation!  I was able to type ctrl-opt-a with the 3 keys from 3 different keyboards!

After a bit of digging, I found out that your KeyRemap4MacBook pref was responsible.  Can you explain how you do this?

Thanks again,

 David

Hi,

KeyRemap4MacBook can change keys to modifier such as "return to command".
For these modification, KeyRemap4MacBook hooks input device drivers and
treats modifiers by itself.
In this process, KeyRemap4MacBook merges modifiers on all keyboards to one.
