ABSTRACT:
A method and apparatus providing visual feedback to a computer user while dragging selected text is described. As its first step, the processing logic creates a text object from the selected text once the computer user has initiated a drag. Simultaneously, the selected text is visually de-emphasized. Secondly, the processing logic snaps the text object to the cursor so that the text object follows the cursor without obscuring text at the insertion point. Finally, when the computer user selects the final insertion point, the selected text is visually zoomed from the source location to the final insertion point.
