I wonder if anyone can help me with this:

I have written a macro that the user can invoke using a
keyboard shortcut. The issue is that I would like the
macro to do something different depending on whether the
user presses "l" or Shift-"l" (i.e. "L"). Of course, if
the Caps Lock key is on, and the user does not notice, the
actions will be reversed. I'd like to be able, in the
macro, to test whether Caps Lock is set on.

Any thoughts? Sorry if this is a total "duh" question.
