Keyboard with pause/break button.

Clearly I did't know about the pause or break button in modern PC Keyboard. Suddenly I watch a video and came to know about the features of that button.

1. Some games still using this button for pause the game.
2. Microsoft using it (window key + pause/break) to hot key to System Properties page.
3. Primary use of it was to communicate through tele-printer. It was used to break the circuit.
4. Now a days it's a free key which you can map to use as a hot key or can use as a key to run macro.
5. ctrl+alt+break used to toggle to remote desktop session.
