Hmmm, yes, and out of interest I just questioned a Australian correspondent
of mine who reported that her keyboard too was unlike the US layout with
regard to number placement (for example no key to the left of the "1" / "!"

Yes... for example the French saw a need to swap two plain letters on
regular keyboards. I think it's important to respect everyone's culture and
traditions but at times the French keyboard has challenged that belief of
mine. I'm sure many of our French friends have had the exact opposite
experience, know exactly what that feeling is like, and will forgive my fit
of intolerance there :¬).

Oh, yes, and China and Arabia as well, if at all possible.

I think so. I think it's important to start with thinking about *what* you
want. For example; on my sequencer the lower row of keyboard keys affects
effects on the drums. On a NL keyboard this runs like;
while on a US one it goes;
In order to be able to use the same interface in terms of key-positioning on
both I use msg.which() there and skip the "]" on the Dutch one, that way
it's the same. For other applications, like yours, the labeling on the keys
is more important and I'd use the ascii value since that is actually what
you are trying to refer to.
It's my opinion that Spencer did a amazing job at the updated HID
implementation (which includes the keyboard) and that this is one of the
cleanest aspects to ChucK. I find it very pleasant to work with and to me it
seems like it's been done with great care, I'm quite sure these options are
there on purpose and with exactly this type of question in mind. So far you
haven't encountered a UK DVORAK keyboard but I bet those exist and
anticipate those would throw off your "numbers or letters" plan completely.
It's very easy to overlook the tricky nature of this problem since we are
all so intimately familiar with our own keyboards. I remember I was looking
at a (Dutch) television quiz years ago and the hostess asked "what character
do you get when you press shift plus 2 on a computer keyboard". According to
her that should be a "@" and whatever the contestant answered was wrong (for
me it's a quotation mark). Somehow whatever process determined those
questions completely overlooked the bewildering range of keyboard layouts
that are out there (I thought it was a bit unfair). If you think it's tricky
now; have a look at the keyboard layout settings in your favourite OS; there
are different models from various manufacturers and most of those can come
configured for a huge range of languages. I wouldn't be surprised if there
were 5 digits worth of keyboard layouts that we might encounter in the
So... yes, ascii should be the way to go, I think that would make your
problems go away, at least until you get users that have a different
character set configured. I have no idea at all how to deal with that.
