You should make clear that this map is US English, e.g. rename it to
usKeyCodeMap or similar.

Also suggest adding a reference to the bug to get rid of this table as soon as
Chrome supports KeyboardEvent.code.

In fact, to avoid confusion, I'd suggest prefixing the key names in here with
"Vk", so it's clear that they're not directly comparable to the values listed
for PPAPI (e.g. under a French layout, you will display KeyA for JS but KeyQ for
PPAPI)

I don't understand this comment; what's it got to do with the layout?  VKEY
values don't distinguish, so you have to actually look at the
KeyboardEvent.location to determine which it is.

The 'code' name for this key is AltRight, not RightAlt.
