Abstract

A method is described which does not require the user to press additional keyboard keys to specify the significance of a pointer position when using a mouse. The position of the pointer on the screen of a display device can have two meanings: the location of an object to be selected or simply a location to which the text cursor is to be moved. Rather than distinguish between these meanings by keyboard keys or varying numbers of presses of the mouse button, the mouse has two buttons. In the new method if the left button of the mouse is pressed, the object at the cursor location is selected. If either mouse button is then held down while the mouse is moved, the text cursor is moved along with the pointer, as though moved by the cursor keys. As long as the activated button remains pressed, the text cursor and pointer coincide.
