Jim,
Is there a list of common keyboard assignments like this?

With the single exception of F1, which is always Help, there really isn't.
And, most PC keyboards have a special key called Fnc or F-Lock or just F for
Function, which when you hold it down will change what happens when you
press one of the 12 function keys to a machine brand or keyboard specific
assigned function such as opening up your email client, or browser, or
search, or print, or whatever. Even here I looked at 5-keyboards I have here
that have pictures of what these do (a Microsoft keyboard, an IBM ThinkPad,
a Toshiba laptop, an HP and an Acer Aspire) and in every case they are all
totally different.
At one point, a very long time ago, IBM tried to suggest some common
guidelines (along the lines of Apple's HIG), but nobody ever followed them
and today, even though IBM still makes PCs under subcontract, they sold out
their PC line to Lenovo a couple years ago.
So, as far as F2 to F12 as well as Ctrl-, Shift- and Alt- combinations of
these (meaning holding down, for example, the Ctrl key and pressing F2)
there is no suggested or pre-assigned functions. You application is free to
use these in any way you wish, which is probably why it's important you use
the F1 key for Help, so users can depend on what to press to figure out what
you've assigned the other keys to do. ;-)

F1 is universally used by all programs on PC as the Help key, so I
wouldn't
use it for any other purpose than to launch your help, as a typical
Windows
user would expect this. Other raw function keys have different
meanings
depending on keyboard or program. However, to the best of my
knowledge,
keystrokes are only sent to the top window. So if your application
is the
top window, you can interpret the key any way you want. If your app
is not
on top, it won't receive the keystroke.

Thanks everybody.
I have set the HELP palette to open with F1 (regardless of platform)
and am leveraging F2, F3, F4 for my own nefarious purposes.
The real reason I am having to use the F keys is because modifier
keys (Ctrl, Alt/Opt, Command, Shift) don't produce rawKeyDown
signals on Mac. This is actually a bl**dy nuisance as it seems
more naturalistic for my end-users to be able to switch from
Sanskrit consonants to vowels with the Shift key than an F key:
but, short of having a punch-up with Steve Jobs, that is the way
things will have to be.
