Different kinds of ohnoseconds reflect the nature and use of specific technologies. For example, a common kind of ohnosecond used to happen a lot with earlier versions of Microsoft Windows. Those who did not adequately back up their work could easily lose a lot of data just by pressing the wrong key. Newer versions have different features to mitigate some of the problems with user errors and to make data more persistent as it is entered.

Other kind of ohnoseconds happen when a user just doesn’t pay attention to the controls for a particular system. Many different kinds of technologies on computers, mobile phones and tablets have delete keys. Some of these may have backup commands or other screens that come up to confirm erasing something, so that the user has another chance to reconsider whether they pressed the right button. Although software often attempts to reduce ohnoseconds, user error can never be completely eliminated, so ohnoseconds will always be a part of working with technology.
