Of course you have more experience with this.

I never seen this possibility to enter the scan code before. From the 
documentation I read that this is new inW2k and XP. I also read that
"the mappings stored in the registry work at system level and apply to 
all users. These mappings cannot be set to work differently depending on 
the current user".

As far as understand this is not something you then can use for problems 
specific to Emacs.

And - or do I misunderstand this - more important: what you refer to are 
remapping the *scan codes* and my code used the *virtual keycodes*. That 
is what is used in Emacs today.

Perhaps, but is not that on another level? Are we not adressing issues 
within Emacs and how Emacs interacts with the system?
