Hi, Glenn, Giuseppe-

I'm in the process of doing exactly that... splitting Glenn's table out 
into different types of keys, and marking up the candidates for 
inclusion for DOM3 Events Key Values set.  As Glen and I discussed 
before, some of these are duplicates of existing key values, for 
example, and others are for specific characters, which aren't necessary 
with DOM3 Events' KeyboardEvent model, which simply uses Unicode for 
such characters.  I already did this process for an earlier version of 
this table, and I'm documenting my process this time, to make it clear 
which I'm adding and why I'm leaving off the others.

So far, I've found approximately 70 new values that are unique to media 
remotes (or similar devices), and I have already added most of these to 
the spec.  Please see the first rough draft in the DOM3 Events Editor's 
Draft, all marked "Media", starting with the 'VolumeDown' key [1].

I should be done by tomorrow, and I'll reply on this thread.
