Sometimes you may decide that you would like to add a TOC entry to a topic file that does not yet have one. Or you want to add an additional TOC entry for a topic that already has one. You can do this with the TOC Link option in the New Topic dialog.
Method 1: Dragging topic files into the TOC
Dragging a topic file into the TOC from the Topic Files section will also create a new TOC entry for that topic file. It doesn't move anything. It just creates a new TOC entry. You can also do this with multiple files. Use SHIFT+Click and CTRL+Click to select multiple files, then drag them into the TOC.
Method 2: Creating a new TOC entry as a copy of an existing entry
You can also create a new TOC entry for a topic that already has a TOC entry by holding down the SHIFT+CTRL keys and dragging the original TOC entry with the mouse to the position where you want to insert the copy. Instead of moving the original entry this will then create a new TOC entry pointing to the same topic. This only works for topics that already have TOC entries, of course.
Method 3: Use the TOC Link tool
The TOC Link tool in the Insert New Topic dialog creates a new TOC entry for a topic file. Note that topics can have more than on entry in the TOC, because TOC entries are really just links pointing to topic files. They are not part of the topic.
Tip – locating the topic ID:
You can find the ID of any topic by selecting Topic Options to the left of the editor window and checking the Topic ID: field there.
1.Click in the TOC where you want to insert the new entry and select the Add Topic tool in .
2.Select TOC Link on the left and click on Link to Topic in this Project.
3.Select the topic ID of the topic you want to link to in the Target Topic: list. You can optionally also select an anchor to scroll to in the Topic Anchor: field if the target topic contains anchors.
4.Click on OK to insert the link.
