Abstract
A data conferencing system includes at least two computer workstations linked by a data network. Each computer workstation is able to store and display an electronic sheet, the electronic sheet being logically divided into a set of cells, each cell being able to contain a single character. A user can select a portion of the electronic sheet, a portion comprising at least one cell, and then perform different editing operations on the selected portion of the electronic sheet. Updates resulting from editing the electronic sheet are then distributed to the other computer workstations in the data conferencing system, so that all the workstations in the data conferencing system share the same electronic sheet.
