I didn't get any response to these questions so I decided to try
again. Does anyone has a piece of advice on how to approach this.
Mainly, if my keyboard has no Shift, Alt, Caps, Ctrl keys, and I'm
never going to have two keys pressed at the same time - should I use
Layout Manager? The application will need to be able to remap my
keyboard so I was wandering if a native driver can expose a function
that app can call to load different mapping table? Is there an example
source code that does not use Layout Manager? I looked at examples
that come with PB but I didn't see any.
