How to specify triggers for real time synching

[three_jeeps]

I've written two synch profiles in FFS:
c:\foo\* mirror to j:\foo\*
c:\foo\* mirror to k:\foo\baz\*

These work fine when I run them manually.
How can I specify for them to run in real time when 1)any file in c:\foo is modified or 2)a new file is created in the foo directory?

more precisely, I can't figure out how to 'write the trigger' in FFS real time to run the synchs.
Any help/pointer is appreciated.
