Feel free to rename this bug report as appropriate.

And I'm not sure if it should be a report about missing doc (or doc I
didn't fine) or a report about bugged behavior.  I'm hoping that what I
don't understand is in fact documented, and I just didn't find that
doc.

emacs -Q

(global-set-key (kbd "S-<f10>") 'forward-char)

C-h w forward-char  ; Says it's bound to <S-f10>

But Emacs doesn't recognize that key at all.  E.g. `C-h k' followed by
Shift with function-key <f10>: the key isn't recognized.

I looked in the Emacs and Elisp manuals, checking index entries that
have "shift" or "function key" in them, but I didn't notice anything
that explained why that key isn't recognized.

But if I do the same thing with (kbd "S-<f3>") there's no such problem.

Is this a product bug?  A doc bug?  Neither?  Is it perhaps
platform-dependent?  I see this behavior also in older Emacs releases,
so it's not new.
