Another question ("Flagger???")

[Elittdogg]

If I wanted to be able to "flag" (something like an event marker) a point (in time) in the data/output, how would I do that? I currently have no script for this nor do I know where to begin to look in the help menu. Basically, (if you've seen my previous thread) if there are objects on the wall, and I need to be able to determine when I get to each object (in the course of my scanning of the wall) how would I mark that so I could see that in the data?

If that's clear, then ignore what's next, but essentially, if I'm going from point A to point B to point C etc. is there a way to "flag" a point in the data for when I get to point A, B, C, etc. Like if someone were holding a clicker or an event marker.

I hope that's clear. Thank you for the help.
