In general, the toolbar buttons represent shortcuts for menu commands. Excel employs the metaphor of a notebook, with each tab in the notebook referencing a separate spreadsheet. By default sixteen sheets are opened with every spreadsheet. Access the different sheets by clicking on the tab for that sheet. Select Rename, then type the new name for the sheet in the dialog box.
Data are easily copied and linked from one sheet to another.
Once a cell is selected, you may type text, numbers or formulas into the cell. Cell contents may be formatted using the Format menu. Edit cell contents either within the cell itself or from the formula bar at the top of the window. Select a block of cells by clicking and dragging the mouse across the cells to be selected. If you position the cursor on the perimeter of the outline, it changes to an arrow.
