Need to change a check that you've already entered? Suppose that you make a terrible mistake, such as recording a $52.50 check as $25.20. Can you fix it? Sure. Just use the arrow keys or click the mouse to highlight the check transaction that you want to change. Use the Tab and Shift+Tab keys to move the cursor to the field you want to change. (You can also select the field by clicking it with the mouse.) Then make your fix. Click the Enter button when you finish or press Enter on the keyboard.
