Menu items that appear dimmed are unavailable. They are available only under certain conditions.
An underlined character in a menu name or item is called a mnemonic. The sequence of keys listed to the right of some menu items is called a shortcut key.
Mnemonics and shortcut keys provide quick keyboard access to menu items.
To choose an item from a pull-down menu using the menu's mnemonics:
Hold down Alt and press the underlined letter in the menu's name.
Press the underlined letter in the menu item's name.
