The text has always been an important recording channel for the development of human civilization. The delete text function is essential. The current method of deleting text is to press the delete button to complete the operation. It does not meet the user's need to delete large amounts of text. This article focuses on a new interactive approach to this problem. We consider problems and find solutions from the perspective of zero-order position control and first-order rate control. Through experimental design analysis and comparison, the new keyboard interaction method greatly improves efficiency and user experience. This article hopes to evaluate the usability of the new keyboard through usability studies.
