Replacing a Tag Set with Another
You can change certain markup tags to other markup tags, provided the other tags are valid in the same location. The Change Markup dialog box lists the tags available for substitution.
To replace a tag set with another:
1. With your document open, place the cursor to the left of the tag set you want to change.
2. From the menu bar, choose Edit > Change Markup. The Change Markup dialog box appears with the available choices. These are the only tags in the document type allowed in this context to replace the selected tags. If the dialog box selection list is empty, no other tags in the document type can replace the selected tag.
3. Click the tag name of interest and then click OK .
4. To reverse the change, from the menu bar, choose Edit > Undo.
5. Click Cancel to close the dialog box.
