I am using InDesign CS5.5 on a 24-inch iMac running Mountain Lion. Recently a curious behaviour has begun and I suspect I have unwittingly done a key combination or something to turn it on. Now I want to know how to turn it off.
Whenever I create a new InDesign document, instead of opening in a simple window with the first page shown in the middle of that window, now my window has a column running down the left-hand side with the heading “Structure”. I am sure this column has useful features for some people, but I have not yet seen any way that I can use it. I can close it by dragging the divider between it and the main part of the window to the left, but I would prefer not to have to deal with it in the first place.
How can I go back to not having it appear? And, assuming there is some useful feature of it that I might want to use on some occasion in the future (please tell me what it is!), how could I turn it on in an existing document?
This seems such a simple thing, yet I cannot fathom it out. And (says he, somewhat red-faced) I have been using InD since version 2!
