Yes, scan code AND virtual key codes. I do not mean to process the scan 
codes (I would not dare ;-)

I took a look at how RegisterHotKey was used in Emacs. It post the 
message back as a WM_KEYDOWN with just the virtual key code and no 
modifiers. Could not the same thing be done in the low level hook I have 
suggested? Or is there something I do not know that must be done?

Maybe you are right, but my gut feeling is that users on w32 expect the 
program the use to do this. There are at least some example of code 
doing things similar to my suggestion.

And it looks to me like things have changed over the years. The low 
level keyboard hook I have suggested that we use is not available in 
older versions of ms windows. (If I remember correctly it is available 
from w2k and onwards.)
