FIELD: information technology.SUBSTANCE: word processing is implemented in a cross-browser runtime technology and provides a rich set of editing features comparable to that of traditional stand-alone word processors. A word processing program displays a document in a window. Upon detection of the placement of an insertion pointer within a paragraph of text in the document, an editing surface is created overlaying the paragraph in the window and containing the contents of the underlying paragraph. User input is monitored by the word processing program while the editing of the contents is processed by the editing surface. When editing is complete, the modified contents of the editing surface are copied into the document and the editing surface is destroyed.EFFECT: reducing the required amount of memory and faster operation.17 cl, 8 dwg |
