The specific actions for DITA topic documents are:
You can also reference elements at sub-topic level by pressing the Sub-topic button and choosing the target.
A new step will be inserted in either one of the following contexts:
The DITA conref attribute provides a mechanism for reuse of content fragments. The conref attribute stores a reference to another element and is processed to replace the referencing element with the referenced element. The element containing the content reference acts as a placeholder for the referenced element. The identifier for the referenced element must be either absolute or resolvable in the context of the referencing element. See here for more details.
Oxygen will display the referred content of a DITA conref if it can resolve it to a valid resource. If you have URI's instead of local paths in the XML documents and your DITA OT transformation needs an XML catalog to map the URI's to local paths you have add the catalog to Oxygen. If the URI's can be resolved the referred content will be displayed in Author mode and in the transformation output.
A content reference is inserted with the action Insert a DITA Content Reference available on the toolbar Author custom actions and on the menu .
In the URL chooser you set the URL of the file from which you want to reuse content. Depending on the Target type filter you will see a tree of elements which can be referred (which have ID's). For each element the XML content is shown in the preview area. The Conref value is computed automatically for the selected tree element. After pressing OK an element with the same name as the target element and having the attribute conref with the value specified in the Conref value field will be inserted at caret position.
According to the DITA 1.2 specification the conrefend attribute can be used to specify content reference ranges. This is a very useful feature when referencing multiple consecutive steps or list items. If you use multiple contiguous sibling selection the conrefend value will also be set to the value of the last selected ID path. Oxygen XML Author will present the entire referenced range as read-only content.
Split Cell Below - splits
the cell from current caret position in two, inserting a new empty table cell below. Note
that this action works only if the current cell spans over more than one row. The row span
of the source cell will be decreased with one.
All actions described above are available in the contextual menu, the DITA submenu of the main menu and in the Author custom actions toolbar.
