Pretty simple question : Map quest display

[aszy]

Good day all.
In the Carbonite map, I have little document-like looking icons representing quests from a database. I have a full stable of toons, and only one has these icons showing. I'd like to know how / where to toggle the display of these quest icons off and on. I have spent way too much time playing around with it and figured I had just better ask.
Thanks in advance.
