Abstract: A computerized spreadsheet automatically calculates a function using a set of selected cells as the cells are selected and immediately displays the result in real-time, without requiring entry of a function into a cell to perform the calculations. The computerized spreadsheet has multiple cells which are selectable by an indicator, such as a pointer or highlight bar. As the author selects one or more cells, an auto-calculator automatically calculates a preset function using the one or more selected cells and displays the result. For example, suppose the function is to sum all the values in a group of cells. As the author selects the cells within the group, the auto-calculator quickly computes the sum of the presently selected cells and displays the result. If the author changes the selection, the calculation is continuously updated and displayed in real-time. In this manner, the author can view intermediate calculations without having to write or embed a formula for them within the spreadsheet.
