Chapter 111 Using the Keyboard Your NAV50 has a close-to-full-sized keyboard and an embedded numeric keypad, separate cursor, lock, function and special keys. Lock Keys and embedded numeric keypad The keyboard has three lock keys which you can toggle on and off. The embedded numeric keypad functions like a desktop numeric keypad. It is indicated by small characters located on the upper right corner of the keycaps. To simplify the keyboard legend, cursor-control key symbols are not printed on the keys. Lock keyDescription Caps Lock When Caps Lock is on, all alphabetic characters typed are in uppercase. Num Lock + When Num Lock is on, the embedded keypad is in numeric mode. The keys function as a calculator (complete with the arithmetic operators +, -, *, and /). Use this mode when you need to do a lot of numeric data entry. A better solution would be to connect an external keypad. Scroll Lock + When Scroll Lock is on, the screen moves one line up or down when you press the up or down arrow keys respectively.
