keyup message is send with the arrowkey - why?

[Tiemo Hollmann TB]

Hello,

I have a field where I have different actions on entering chars (a-z) or
using the arrowkeys. The events for the standard chars are handled in
keydown/up and the arrowkey in rawkedown/up. The rev docs tell me: "If the
key pressed is the Return, Tab, Backspace, Delete, or Enter key, an arrow
key, or a function key, no keyUp message is sent." But I am experiencing
something else. When pressing the arrowkey (down) in a field WITH content,
first the two rawkey messages are send and after that also a keyup with the
last char of the field content as the key is send. (which troubles me a
little bit).

Is this a bug, a wrong doc or a wrong me?

Thanks for verifying

Tiemo
