"Use Security" checkboxes in macro designer?

[tfe62]

What does the "Use Security" on or off checkboxes do in Macro Designer? I can't find it in the help files in either AHP or Smart Macros. Nor is it on Wiki. Does anybody know what this function does? It's right at the top when you click on the add macro + sign.

This enables one to use security modules for triggers.
