In earlier versions of Traction, the Erase function was handled in this
tab. Now it is done within the interface. Erase Articles is now a tool
available through the Collector, or the Tools or Context Menus (see below):
Tools Menu - Right Column
Context Menu
Notice that the option appears in the Article and the Page level. Article
selection will only erase the article over which you clicked. Page selection
will erase all articles on the page.
