Referencing common footnote?

[Manoj Rajagopalan]

hi all,

  The user guide points out how to insert a footnote but I can't figure 
out how to reference the same footnote from two different locations.

  Is there a better way than to create a label (in a new category) and 
insert a reference to it formatting it as a superscript?

Thanks,
Manoj Rajagopalan
