ABSTRACT:
A word processor is provided with a handwriting text processing function. A display displays document and text processing information. A pointing device enters handwritten text processing figures on a display. A memory stores text processing instructions associated with an text processing figure drawn on the screen. A direction in which the pointing device is moved on the screen to draw a figure, a length of the drawn figure on the screen, and/or which of several regions of the display the pointing device is presently pointing to are determined and used to distinguish different text processing functions associated with the same basic handwritten text processing figure. The word processor uses this information to selectively execute different kinds of text processing instructions such as an up-scroll of the screen, a down-scroll of the screen, a display of document head, a display of document tail, a display of underline, a display of line head, an arbitrary cursor movement, and a cursor shift on the same line.
