Using Option Buttons

Option buttons (or radio buttons) enable you to make a single choice from a list of possible command options. For example, the Print Range options displayed in figure below enable you to choose which pages of your document you want to print. The active option (the Page Range option in the figure below) is indicated by the small filled-in circle.

To select an option button with the mouse, click the circle for the option you want.
To select an option button with the keyboard, press Alt + selection letter for the option you want.

For example, in WordPad, press the keyboard shortcut (Control + P) to activate the Print dialog box or activate the menu bar with Alt + F, then P for the Print dialog box. Use the Tab key to navigate to the Page Range section and use the arrow keys to make your selection or to choose the desired option button. Tab to the Apply button to accept the selection, click Enter. When you are ready to print, tab to the Print button and click Enter.
