A NEW icon beside a view indicates that new notes have been added to that view that you haven't read. Click the view that contains the notes you wish to read. You will see a new window, with a list of note titles in the selected view as explained below. Within your selected view, you will see a list of notes. Turquoise squares indicate unread notes.
Red squares indicate that the notes have been read.
Blue squares indicate that a note has been modified. Indented notes are Build-On notes. A Build-On is a separate note, but is connected to the note it is building from. Since note titles are links, they may appear as visited or unvisited. Click the colored square or the underlined title just like any standard Web link.
