In addition to using a mouse, you can use keyboard shortcuts to select menu commands and complete dialog boxes.
Every menu title and most commands on a menu have an underlined letter, called a mnemonic. To select a menu, press ALT + <mnemonic for the menu title>. To select a menu command, press the mnemonic key for the command. You can run some commands by pressing Ctrl plus another key or a function key. These shortcuts are listed on the menus.
To navigate to different boxes and buttons in a dialog box or property sheet, use the Tab key. To select different tabs in a property sheet, use the Tab key to move to the current tab, then use left and right arrow keys to select other tabs.
