Icon: Yellow and white striped cone?

In some of the sample databases, there are a few documents represented by an unusual icon: a yellow and white striped cone, like a traffic cone.

What does this signify, and how does one assign such an icon to a particular document?

That icon does not have a particular meaning, and isn’t a choice within the program.

You can replace any icon within one of your own- including a traffic cone. Select the item you want, and open “Show Info” from “Tools”. Select the icon that appears there, and drag the new one into that space.

Thank you.
