Option buttons

Option buttons (also called radio buttons) are a set of two or more mutually exclusive options. The name
radio button comes from the buttons on old-fashioned car radios, where pushing a button to select a
station automatically unpushed whatever button was previously pressed. Figure 2-11 shows a couple
option buttons available on the Start Menu tab of the Taskbar and Start Menu Properties dialog box
(which opens when you right-click the Start button and choose Properties).
Figure 2-11: The Start menu and Classic Start menu options here are mutually exclusive, as indicated by
the option buttons. You can select one or the other, but not both.
Choosing an option button is simple, just click it. Often you can click the text next to the radio button,
which provides a larger target. Choosing radio buttons with the keyboard is a little trickier. Within the
dialog box, you need to press the Tab or Shift+Tab keys until one of the radio button options is selected
(has a little gray border around it or its label). Then you can use the arrow keys to move that gray border
to the option you want. To move out of the radio button group, press the Tab or Shift+Tab keys.
