A break may refer to any of the following:
1. Sometimes abbreviated as Br, the Break key is a computer keyboard key (shown right) that usually shares the same key as Pause. It enables a user to break the computer from a pause or other halted state. To use the break function, you may either press the break key alone, or press Ctrl at the same time as the break key. For example, pressing the Pause key stops the computer as it boots, pressing it again, breaks out of that pause.
Where is the Break key on the keyboard?
The Break key may be abbreviated as Br or Break and is found with the other control keys on the keyboard. Below is an overview of a computer keyboard with the Pause key highlighted in blue.
