Patent number: 11704532Abstract: Techniques are disclosed for a hybrid undo/redo for text editing, where non-linear undo and redo operations are performed across dynamic regions in a document and linear undo and redo operations are performed within the dynamic regions in the document. In an example, the hybrid undo/redo may be achieved by maintaining respective region offset values for the dynamic regions created in a document by the edits made to the document. In operation, the respective region offset values associated with the dynamic regions can be used to negate or otherwise counteract the effect of edits made in the dynamic regions.Type: GrantFiled: November 15, 2021Date of Patent: July 18, 2023Assignee: Citrix Systems, Inc.Inventors: Yajun Yao, Yuan Bai, Juanjuan Chen
