(I manually cleaned up some quoted-printable damage in the above.)

The numeric pad keys send different characters depending on whether Num
Lock is set.  I usually have it on.

Alt-7 sends the same thing (Escape-7) both for the 7 key above Y and U
and for the 7 key on the numeric pd.  With Num Lock off, that key acts
as the Home key; Home sends ^[[1~ and Alt-Home sends ^[[1;3H, where ^[
is Escape.

There are probably some subtleties I'm missing.  I rarely use either Alt
or AltGr.  I don't often need to type non-ASCII characters; when I do,
my most common approach is to use vim digraphs.  Possibly I could find a
method that's more convenient, but so far I haven't been motivated to do
so.
