Hi, folks-

Sorry, it took me longer than I thought... I'm at a F2F meeting, which 
is distracting. :)

I've now added around 70 new equivalent key values to the list [1], and 
changed the names of several others to be more broadly applicable.  I 
have changed names for several of the VK_* values, to be more clear in a 
general context, which I hope is acceptable.

Attached is my breakdown of the table that Glenn provided, explaining my 
process.
