Totally disagree. Which is easier?
if (keyThatWasPressed.toLowerCase() == "g") << for your "99%" of
people
or...
if (keyThatWasPressed.toLowerCase() == "g")
{
...Now figure out if shift and/or capslock is down..
}

Subject: Re: [Rails-spinoffs] event.keyCode broken in prototype?
I'd say, returning letters consistently cased makes sense.
element.nodeName is always returned in capital letters for the same
reason - because 99% of the time the case doesn't matter, and you really
don't want to be calling case-conversion functions when you just want to
see if something == a letter. For the other 1%, I guess yes, people are
supposed to test for shift and/or caps lock.
