what is num lock and scroll lock
Num Lock or Numeric Lock (â­) is a key on the numeric keypad of most computer keyboards. It is a lock key, like Caps Lock and Scroll Lock. Its state (on or off) affects the function of some of the keys, and is commonly displayed by an LED built into the keyboard. A keyboard with Num Lock turned ON.
Recently, while reviewing customer comments related to scrolling in a spreadsheet, I discovered that a lot of folks have run into this issue. Scroll Lock is a toggling lock key on the keyboard, just like the CAPS LOCK key. Once pressed, Scroll Lock is enabled. To turn it off, simply press the Scroll Lock key again.
