			Message Map The message map uses icons to represent the messages in a user's folder. Each box implies a message; the boxes are drawn in reverse chronological order. The currently-selected message is blue, and other messages in the same thread are highlighted with a lighter blue. If the user executes a search, messages that do not satisfy the search are drawn as lighter "ghosts." The user can select attributes (same author, unread, sent, attachments) to be highlighted in orange or marked with a "dog ear" graphic. Toggling these settings allows the user to quickly see relationships among messages in the folder.
