The invention's features improve the user interaction of Caret and Selection manipulation in text GUI components. The Precaret, like the Caret, indicates a position between text characters, but unlike the Caret, the Precaret continually tracks the Cursor, jumping from position to position to indicate exactly where the Caret will be placed when the mouse is clicked. The Gapper visually indicates a gap of one or more white space characters in the text or a gap of white space between paragraphs; the Gapper tracks either the Precaret or the Caret, whichever moved last. An enhanced Cursor switches to a less-obtrusive form while it is over text so as not to obscure the position of the Precaret while moving the mouse or the leading edge of the Selection while dragging the mouse. The Caret and Precaret change shape to indicate a special feature of a position within the text, such as the wrapping of one text row to the next. |
