A+Numeric+Keypad

=__A Numeric Keypad __= Numeric keypads are a separate set of keys on some keyboards that contain the numbers 0 through 9 and a decimal. Numeric keypads make it easier to enter large amounts of numeric data. Often, the keys on the numeric keyboard also serve as cursor control keys. Their meanings, therefore, depend on what mode the numeric keypad is in. In numeric mode, they represent numbers; in cursor control mode, they are like arrow keys. Keyboards that support these double functions contain an additional key that enables you to switch modes. The name on many keyboards is labelled Num Lock.
