All actions described above are available in the contextual menu, the
XHTML submenu of the main menu and in the Author custom
actions toolbar.
A drag and drop with a file from the
Project view or from the DITA Maps
Manager view to a DITA topic document that is edited in Author mode
will create a link to the dragged file (the xref DITA element with the
href attribute) at the drop location. A drag and drop with an image
file from the default file system application (Windows Explorer on Windows, Finder on Mac OS
X, etc) will insert an image element (the image DITA element with the
href attribute) with the location of the dragged file at the drop location,
like the Insert Graphic toolbar action.
