However, what the keyboard combination accomplishes is unique based on the context in which it's used.

Bradley, as the chief engineer of the project and developer of the machine's, had originally used + +, but found it was too easy to bump the left side of the keyboard and reboot the computer accidentally. According to his own account, Hallerman, who was the chief programmer of the project, therefore suggested switching the key combination to + + as a safety measure, a combination impossible to press with just one hand on the original. The feature was originally conceived only as a development feature for internal use and not intended to be used by end users, as it triggered the reboot without warning or further confirmation—it was meant to be used by people writing programs or documentation, so that they could reboot their computers without powering them down. (former ) remembered it as 'just something we were using in development and it wouldn't be available elsewhere'. The feature, however, was detailed in IBM's technical reference documentation to the original PC and thereby revealed to the general public. Bradley viewed this work as just one small task out of many: 'It was five minutes, 10 minutes of activity, and then I moved on to the next of the 100 things that needed to get done.'
