Unclick is a term, increasingly applied in the context of computing, in which a computer user un-chooses or de-selects a specific preference, typically by moving a cursor over a selection, and pressing the left mouse button. As a result, the check mark image or dark circle inside a Checkbox or a Radio button is removed. While in January 2012 the term unclick is generally not formally defined in dictionaries, the term has been used in popular parlance in countries such as the United States, Britain, Brazil and Canada.
