Unformatted text preview: Excel Primer To Start Excel : Double click on the Excel icon or select the program from the menu (often found under Recent Applications). A blank workbook page should appear containing a grid of cells with letters labeling columns and numbers labeling rows. If you dont have a blank Excel sheet you can obtain one by selecting File from the uppermost menu, and then New. On newer versions of Excel you will first open the Project Gallery and then open the Excel Workbook. To Enter Numbers and/or text: Click in the cell that you wish to type in. Enter numbers or text headings as desired. You can type in the formula bar: or you can type directly into the target cell. To enter your new information, click on the green or press the Enter key. If you change your mind and you want to leave the contents of the cell unchanged after you have started typing, just press the red X button. Your new text will be discarded.

This option can be selected on the toolbar (for example, B stands for bold, click on it to choose it) or by pulling down the Format menu and choosing Cells .
