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 <Num Lk> (the Num Lock indicator lights up).

Figure 1. Embedded Numeric Keypad

Some key combinations can be used whether or not the keypad is activated.

NOTE: On an external keyboard, use <Scroll Lock> with the appropriate keys if the External Hot Key option is enabled in the System Setup program.

Use the numeric keypad combinations in Table 1 to enable and disable several numeric keypad functions.

Table 1. Embedded Numeric Keypad Key Combinations
