Embedded Numeric Keypad

As you work, you may want to use the embedded numeric keypad (see Figure 1) to enter numbers in spreadsheet or financial programs. The embedded numeric keypad shares some of the keys on your computer's keyboard. On these keys, the number and symbol characters of the numeric keypad appear in blue to the right of the main keypad characters. To activate the embedded numeric keypad, press <Fn><Pad Lock> (the Pad Lock indicator lights up while the embedded numeric keypad is active).
