Today's test

[tree@lady.axian.com (Larry Tyree)]

Okay, you guys did so well with yesterday's question, here is one for 
today.

How does one detect the F11 and F12 keys?  They are ignored by Borland
Pascal's KeyPressed and ReadKey routines.  The memory location I
can find out the status of the SHIFT, CONTROL and ALT keys doesn't 
do anything when press them - so what is the story?

If I can solve this puzzle, we can use them for something!!
