The Disclosure Triangle… It sounds like a John Grisham novel, but it’s actually part of the Graphical User Interface found in many applications on the Mac including Mail, iTunes and the Finder.
It looks like this ▶ and is used to show or hide hierarchical information.
I was surprised to discover that a lot of new users, don’t notice it, or don’t know what it means.
In this form ▶ information is hidden. A click on the triangle causes it to rotate downward ▼and reveal information.
Here is an example from the Finder. In the first image the Apple Folder is closed. A single click on the triangle and it opens to show it’s contents.
Now… the triangle holds no secrets.
Have a good weekend.
