WTF Alt-S means different things for appointment

This must break every user-friendliness rule in the book regarding
sane, predictable behaviour.

Alt-S saves appointments if they are not new. However, it sends
appointments when it is a newly created appointment. You could be
dealing with exactly the same appointment e.g. newly created, still
being composed and finalized, but depending on whether you've saved it
and re-opened it, Alt-S could send it out to the recipients before you
want it to.

I'm thinking that it completely defies any manner of common sense for
a shortcut key to map to different functions like that, for the same
thing. Basically, you can't just condition yourself to rely on any
one functionality, you must look up at the menu (in which case, it
isn't a far stretch just to mouse over, which defeats the purpose of a
shortcut key).
