 Shiftkey detecting

How can I detect from BASIC if a key was pressed together with SHIFT (for example SHIFT + CRSR-UP)?
There is a RAM location around $05xx (*) that stores the last pattern of SHIFT, CTRL, CBM but it seems not to work under BASIC. Any tip?

(*) Sorry for not complete info, but I'm at job place, and I haven't +4 docs here wink

I always used $C6 and $0543. Something like:

10 PRINTPEEK(DEC("C6")),PEEK(DEC("543"))
20 RUN

PEEK(1347) is what you seek:

0 for no control keys
1 for Shift (either left or right)
2 for Commodore key
4 for Control key

The key has to be pressed when the PEEK is evaluated, for it to be seen this way.
