Sorry, couldn't tell. I tried several times (in Notepad, another
editor, Word, Windows Run dialog, ...etc.), and could find no
difference at all between the two. They all show a round dot to me.

So you mean the OS (Windows) would buffer all the keyboard actions
during the time Alt is down and send the result after the whole
event (after Alt is up)? Is this documented somewhere (online
sources preferred, please)?
AFAIK, key codes continue to be sent to the application during the
time Alt is down, and it's up to the application to interpret the
result, including whether to disregard the NumLock status or not. By
application I mean the last program down the chain that can get the
keyboard events (including the status of various modifier/special
keys) and get to interpret them.

Again, please tell me where it's documented. Thanks.
