Figure 4—3: Expanding and Collapsing

2.COLLAPSE PSYCHOGRAPHIC SEGMENTS and EXPAND it again;

3.COLLAPSE DEMOGRAPHIC SEGMENTS and EXPAND it again; and

4.COLLAPSE INTENDED MARKETS and EXPAND it again.

Notice how COLLAPSE hides everything under the bar cursor head- line, while EXPAND reveals only the first level under it. You can set a command prefix to make EXPAND reveal more levels.

This exercise also shows that each ThinkTank headline~ represents an outline in its own right. The entire THINKTANK DEMONSTRATION is an outline; each of its first subheadings is the title of an outline; indeed DRINKING HABITS is an outline of its own. Each outline (except the summit, THINKTANK DEMON- STRATTON) is a part of a larger whole.

The bar cursor headline and the outline it represents is called the bar cursor outline. Since the commands you select generally affect either the bar cursor headline or the bar cursor outline, you should develop the habit of moving the bar cursor to where you want your action to take effect before giving a command.
