Dan says:  I haven't ever been able to get "help" like that on Win98, but I
will look on an older Win3.x system which does.  But would I be able to
utilize it *programaitically*, so the app user wouldn't have to do anything?

Dan says:  rather not do that if I can avoid it, (poking to re-set lockable
keys is near my limit), and if there *is* a special handler for the special
windows keys, as I would agree is likely, then 09h & 16h probably (?)
wouldn't deal with them; plus, it's unappealing to make it not likely to
work with other machines.

Maybe I'll try asking MicroSoft (guffaw!)

Thanks.
