About using ink in Excel
If you are using a Tablet PC and Microsoft Office Excel 2003, you can use the tablet pen to add ink annotations or drawings to worksheets. You can use ink to emphasize data in a worksheet or to add handwritten notes to the worksheet.
You can add ink anywhere in your worksheet by using ink annotations to make comments or recommendations. Ink annotations can be shown or hidden. In addition, you can use ink drawing and writing to add a permanent hand-drawn or handwritten piece of ink to a worksheet.
