  • Publication number: 20120180002
    Abstract: Different gestures and actions are used to interact with spreadsheets. The gestures are used in manipulating the spreadsheet and performing other actions in the spreadsheet. For example, gestures may be used to move within the spreadsheet, select data, filter, sort, drill down/up, zoom, split rows/columns, perform undo/redo actions, and the like. Sensors that are associated with a device may also be used in interacting with spreadsheets. For example, an accelerometer may be used for moving and performing operations within the spreadsheet.
