Figure 3.6: Several Browsers

Another way to view a list of items is to use a browser, as shown in figure 3.6. A browser displays several items on the screen (unlike the chooser which only shows one) and has a slider which is used to scroll though all the available options. Selected items are highlighted. Some browsers only allow one item to be selected, while others allow multiple selections and do not automatically deselect a line when a new item is picked. To turn off a selected item when multiple selections are allowed, click on the item, and the highlight will disappear.

One common browser motif uses coupled browsers to describe two-level hierarchies. Selecting a line in the first browser determines the possible selections in the second. An example is shown in figure 3.6 B.
