Key

1. When referring to a computer keyboard, a key is a single button on the keyboard. Letters, numbers, functions, and symbols are all represented on keys.
2. A key is also a tool used to lock and unlock a computer, computer drive or other computer related device. If you have lost the key to your computer device, Computer Hope cannot assist you with obtaining a new one. Contact the manufacturer of the product that is locked.
3. When referring to the computer Microsoft Windows registry, a registry key, or key for short, is a term used to identify an item in the registry, such as HKEY_LOCAL_MACHINE.
4. The term key or keyed may also be used to describe a cable with physical dimensions that causes a cable such as a ribbon cable to be connected only one direction. In some rare cases this may prevent a cable from being properly connected to a drive. For example, the manufacturer of a floppy disk drive may have keyed their connection differently than the cable manufacturer has. In this situation, the user may either be required to purchase a different brand of cable or floppy drive, or modify the key on the cable.
5. When referring to encryption a key is a set of instructions that is used to encrypt and decrypt data.

End key

A key found on keyboards usually below the home key that moves the cursor to the end of the line, paragraph, page, screen, cell, or document depending on the program and where your cursor is currently positioned.

An example of how the End key could be used is to move the cursor to the middle of a line of text and press the End key, which would move to the end of the line of text. Using a key combination such as pressing the Shift key and the End key together would highlight the text from the cursor to the end of the line.
