Numbers can be typed using either the set of number keys at the top of the keyboard or the keys on the numeric keypad. Some keys on the numeric keypad have two symbols. When the NUM LOCK key is activated, the numeric keypad will create numbers when pressed. When the NUM LOCK is not activated, the keys on the numeric keypad move the cursor in the direction indicated by the symbols or words on the keys. The function keys are not standardized in all software programs.
Function keys are a quick way to give special commands within programs.
If you are ever unable to make the keyboard do what you think it should do, check to be sure these lock keys are in the proper position. The indicator light will let you know if the lock is on. How you move the mouse on a hard surface or mouse pad corresponds with the movement of the pointer on the screen. Roll the mouse up, down, and side to side until the arrow on-screen points to an area of the screen. The mouse can be programmed for use by either the right hand or left hand.
