Creating External Links
You can link text in DM 2.0 to a URL by creating an external link:
Highlight text - as you would highlight text in order to copy it.
Click the “Link” button in the center-right of the text editor bar.
Enter a URL in the text box.
Click the “Add” button.
You can confirm the link by checking in the document for collaborators to edit, and then clicking the link to follow it to the web address.
