Patent ID: 7797621

Claim:
A method for effecting alteration of data in a first data cell during a navigation operation between the first data cell and a second data cell; the method comprising: receiving, at a computing device processor, a first input that indicates a user selection of the first data cell; receiving, at the computing device processor, a second input that indicates user navigation from the first data cell to the second data cell; providing, via the computing device processor, a query to the user inquiring whether the user wants to alter a first data value in the first data cell for transfer to the second data cell; receiving, at the computing device processor, a third input that indicates user desire to alter the first data value for transfer to the second data cell; providing, via the computing device processor, an input field for the user to enter a desired alteration of the first data value; receiving, at the computing device processor, a fourth input that indicates a user entry via the input field for effecting the desired alteration, wherein the user entry includes a mathematical operation to be performed upon the first data value; performing, via the computing device processor, the mathematical operation on the first data value to effect the desired alteration to generate a first altered data value; and entering, via the computing device processor, the first altered data value in the first data cell and the second data cell, wherein the entering occurs before or substantially simultaneously with the user completing navigation from the first date cell to the second data cell.
