Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application When text is edited on-screen by pressing a button on a word processor, it may become necessary to edit another portion of text located away from the cursor position currently being edited. many. In this case, instead of moving the cursor up or down one line at a time, typical word processors have keys for moving the cursor at 10 or 20 lines or by the number of lines on the screen. Here, this cursor movement key will be referred to as a scroll key.

The word processor user can use the scroll key to move the text displayed on the screen to quickly find the next part to edit.

BACKGROUND OF THE INVENTION Scroll keys on conventional word processors provide power in increments of a number of lines specified by the word processor, or a number of scroll lines specified by the user of the word processor as one of the optional feature parameters of the word processor. Sol movement or screen scrolling was occurring.

Problems to be Solved by the Invention However, in the conventional method described above, when scrolling occurs on the screen, the number of scroll lines is a fixed width and the screen moves within a physical range, so the word processor user cannot see the current screen. It was difficult to intuitively grasp the content of the displayed text.

Means for Solving the Problem: The width of the scroll caused by pressing the scroll key once is not a fixed number of lines, but a paragraph unit. This may be specified as an option for the word processor's scroll keys.

In the paragraph-by-paragraph scrolling method, if you press the upward scroll key at any cursor position, the cursor will move to the first character position of the paragraph that contains the cursor. Next, press the up scroll key again to move the cursor to the first character position of the paragraph before that paragraph. Pressing the down scroll key moves the cursor to the first character position of the paragraph following the paragraph containing the current cursor.

Embodiment FIG. 1 shows a flowchart of an embodiment of the present invention. The method of searching for the paragraphs before and after the paragraph in which the cursor is located differs depending on the format in which the text of the word processor is expanded into the main memory of the system on which the word processor is running. Generally, information that controls the paragraph is added to each paragraph, including pointers to the preceding and following paragraphs.
It can be easily found using this pointer. For formats without paragraph control information, paragraphs can be separated by page break codes. Therefore, the first character position of the paragraph is the character following the page break code.

Effects of the Invention Editing work in a word processor is generally performed in units of paragraphs, which are one meaningful set. Therefore, when searching for the next editing location, the word processor user can intuitively grasp the content of the currently displayed text by scrolling the display screen paragraph by paragraph. In addition, one paragraph may be several lines, but it may also be larger than the number of lines that can be displayed on the screen, so you can search for the desired paragraph with fewer scrolls, improving the efficiency of editing work.

The functions of the present invention can be applied not only to word processors but also to editors used for creating programs. However, in the case of an editor, one line is one paragraph, so measures such as setting the scroll unit to each function are required.

Claims (1)

[Claims] On the text display screen, the cursor indicating the current editing position was moved up or down the screen in groups of lines, and the keyboard was given the ability to scroll in groups of lines to display text that was off-screen. In a word processor that has the above scroll key, by specifying a paragraph as the unit of line to be scrolled to the scroll key, the cursor moves or the screen scrolls by paragraph each time the scroll key is pressed, and the paragraph A text screen display method that places the cursor at the beginning.
