Embedded Numeric Keypad
As you work, you may want to use the embedded numeric keypad (see Figure 4 ) to enter numbers in spreadsheet or financial programs. The
embedded numeric keypad shares some of the keys on your computer's keyboard. The number and symbol characters are marked to the right on
these keys; the cursor-control functions are marked on the front of these keys. To activate the embedded numeric keypad, press <Num Lk>. (The
Num Lock indicator lights up).
