In NoteCards a "tabletop card" is an arrangement of cards (hypertext nodes) on the screen, such as the 3 cards at the center.
A "guided tour" is a graph whose nodes are tabletop cards (table icons) and whose edges are links connecting the cards. You traverse a guided tour with the control panel at right and the result is a "slide show" of tabletops.
