Anchoring Comment Boxes in Desired Locations

Bill is creating a form using Excel, and he has attached comments to the column headings to remind people what goes in each column. When the mouse pointer is moved over the column heading, the comment box always pops up to the right of the column, which is a problem for those columns near the right side of the screen—the boxes appear off the screen, to the right of the column. Bill wondered if there is a way to tell the comment box where it should pop up.

The short answer is that there isn't any way to control where the pop-up comment box will appear; it always appears to the right, and it's position is always reset every time the pop-up action occurs. If you configure Excel so that comment boxes are always visible (i.e., they don't "pop up"), then you can position the individual comment boxes. You can configure Excel 2007 in this way by following these steps:

1. Click the Office button and then click Excel Options. Excel displays the Excel Options dialog box.
2. At the left side of the dialog box click Advanced.
3. Scroll down until you see the Display options. (Click here to see a related figure.)
4. Select the Comment & Indicator radio button.
5. Click on OK.

If you are using an older version of Excel, follow these steps instead:

1. Choose Options from the Tools menu. Excel displays the Options dialog box.
2. Make sure the View tab is displayed.
3. Select the Comment & Indicator radio button.
4. Click on OK.

The comments should now be visible, and you can position them as desired. The drawback to this approach, of course, is that if you have a lot of comments in your worksheet, the screen can appear quite cluttered. If you change back so that only the comment indicator is shown, then the positions you set are lost, and the pop-ups (when you move the mouse pointer over the cell) again appear to the right of the cell.

Another approach to displaying the comments you want is to use the data validation feature in Excel instead of actual comments. (You can use the Input Message tab of the Data Validation dialog box to set the message to be displayed when the cell is selected.) There are a couple of operational differences between the data validation input messages and the regular comments. First, the message is best associated with the actual input cell, not with any header cell for the column. (This way the message is displayed when the user actually starts to make input.) Second, a cell for which there is an input message does not have a small indicator in the upper-right corner, as is the case with comments.

The benefit to using the data validation input messages is that the message will always be visible on the screen; it does not default to displaying to the right, as comments do. In addition, you can manually position the messages where you want, and Excel remembers that position.
