A system for preventing inadvertent wrapping of a cursor generated on a computer display detects the location of the cursor in proximity with a border of the display and determines whether a user actually intends the cursor to wrap to the opposite side of the display. The system considers a variety of factors to determine whether the user actually intends to wrap the cursor. The time for which the user moves the cursor against the border, the distance that the cursor would have moved but for the border, and the velocity or acceleration with which the cursor approaches the border can all be considered by the system in determining whether or not to permit the wrapping of the cursor. The system automatically generates an indicator signal to permit the cursor to wrap from one side of the display to the opposite side. The user can select the size of the border and determine whether the border will have a color different from the normal display background color to visually indicate the location of the border to the user. The system can selectively enable and disable the border in response to a variety of factors. The user can manually generate the indicator signal by activating a command signal input. The system can operate in a graphical environment where a plurality of display windows are shown on the computer display. The system defines a border for each window to prevent the inadvertent wrapping of the cursor.

A data processor having a page turning function, for managing a plurality of data sets each containing a plurality of data units of different kinds, has an extraction portion, a decision portion, and an output control portion. The extraction portion is used to extract a data unit in a page ahead of the present page in response to a next page instruction, or in a page behind the present page in response to a previous page instruction, and the decision portion is used to determine whether or not the kind of the data unit extracted by the extraction portion is equal to the kind of a data unit in the present page. The output control portion is used to provide the data unit extracted by the extraction portion if the decision portion determines that they are equal to each other, and if the decision portion determines that they are unequal to each other, restarting the extraction process of the extracting portion. Therefore, the page turning operation can be rapidly and easily carried out.

Rapid toggling of application windows to the forefront of a computer monitor. One or more queues are established by a user comprising indicia representative of a sequence of a plurality of open application windows. Sequencial toggling among the windows of a given sequence is accomplished by actuating a mouse pointer positioned to the white space of any window within the given sequence.

The present invention provides a method of turning over a window that is laid over another window in order to peek a content of another window that is laid under the window in a pseudo-three dimensional manner, in a multi-windows computer system. The method includes the steps of (a) selecting a first window from the multi-windows by placing an object on the first window; (b) clicking the object on the first window to initiate an operation of turning over; and (c) dragging the object toward a direction to which the first window is to be turned over so as to unveil a second window that is laid under the first window, whereby enabling to peek a content of the second window.
