Please follow CodingStyle with /* and */ on their own lines. Also, wrapping is
strange, as is capitalization, etc. Please terminate sentences with periods,
and only capitalize the beginning of sentences or proper nouns.

Please be consistent with your line wrapping. The if block above wraps early and
is a rather difficult to scan, while the keycode index goes well beyond 80
chars.
