Insert
Placing the cursor over the Insert command pops up a sub-menu which contains the items that can be inserted. The submenu items of the Insert command are enabled only in Grid View. Items that cannot be inserted for the current selection are grayed out.
The commands of the Insert sub-menu can be used to insert (i) the XML declaration and node types (Attribute, Element, Text, CDATA, Comment, Processing Instruction) in XML documents, (ii) DOCTYPE declarations and external DTD declarations in XML documents, and (iii) DTD declarations (ELEMENT, ATTLIST, ENTITY, and NOTATION) in DTD documents and internal DTD declarations of XML documents.
