Help?!  What is the 'officially approved' way to sense a command-period
(cmd-.) so that a user can interrupt a long operation from the keyboard?
I would like something that doesn't slow down my inner loop too much,
and that would work on all Macs.  A code fragment in any language would
be appreciated -- I'll be working in Think C 4.0 on code segments (for
HyperCard XFCNs), specifically.  Many thanks, and Happy New Year!  ^z
