Creating Captions

---

The default format options of any new captions you create are specified in the Captions tab of the Document Settings dialog box. You may edit these options at any time. The settings affect the current document only.

To create a caption:

1. Click the Text tool .

2. Point in an empty space in a document window.

A caption text box with a flashing insertion point appears.

3. Type a caption.

The text box widens as you type to accommodate the caption.

4. To create a new line, press Return.

5. To close the text box, click outside the text box or select another tool.

NOTE: You can verify the chemical significance of a caption or atom label using the Check Structure command by selecting it with the Lasso or Marquee tool.

By default, captions are considered to be chemically significant if possible. For example, if you create a label like "CH₃OH", you will be able to attach bonds to it (and it will be modified appropriately) even though you intended it to be a label, not a molecule. Moreover, it's values are included in the Analysis Window, which could be confusing. If you try to label structures "A", "B", and "C", the "B" and "C" labels will be marked with a red box because they have "incorrect valences". To fix this, do the following:

1. Select the label with the Lasso or Marquee tool.

2. Control+click in the selection.

3. Deselect the Interpret Chemically command.

Alternately, you can change the default by unchecking the "Interpret Chemically When Possible" option on the Captions tab of the Document Settings dialog box.
