You can use any menu, command, or button by either clicking the mouse or using the keyboard shortcut.
To use keyboard shortcuts:
For menus, press Alt and the underlined letter on the menu name. You can use the left and right arrow keys to move from one menu title to another. Press Enter to display the menu.
For commands in menus, once the menu is open, press the underlined letter on the command name.
Some commands have shortcuts. For example, you can press F4 to display the Alerts Screen.
For buttons at the top of windows, press the function key that displays on the button. For example, press F1 to display online help for that window.
If the function key does not display, on the Preferences menu, point to Toolbar, and then click Keys and Text.
For OK buttons, press Enter.
