The present invention provides a cursor control system for controlling operations of a pop-up menu. The menu comprises a plurality of command regions, each of which has a correspondent computer command. The system comprises a displaying device for displaying the pop-up menu, a computer electrically connected to the displaying device and a cursor control device electrically connected to the computer. The computer comprises a program for controlling image display of the displaying device and operations of the menu. The cursor control device comprises a housing having a recess installed in it, a cursor controller elastically installed in the recess for generating a shifting signal, and a switch installed in the recess beneath the cursor controller for generating a start signal. When a user presses the cursor controller and thus triggers the switch, the program will receive the start signal generated by the switch and then will display the menu over the displaying device. When the program hereafter receives shifting signals generated by the cursor controller, the program will select one command region on the menu according to the shifting signals. And when the user releases the cursor controller and the switch, the program will start executing the computer command of the selected command region.

A system for facilitating the searching of data from an electronic data source. The invention teaches a method for presenting a large number of search terms rapidly and efficiently to a user. Users may scan a large number of search terms, move quickly from one search category to another, select a search term with minimal mechanical input and generate a series of "hits" that meet their search goals. The need to guide the computer with mechanical actions from a keyboard, mouse or other device is minimized. Graphics that distract the user from any task other than selecting hits are eliminated. Users are able to scan quickly and find electronic information with minimum effort.
