How to add margin notes to a Word document.

[Yakbird]

Hi. I'm wondering how to add notes to the right-hand margin of a Word document. The instructions I've seen so far have said 'first select the text you wish to insert,' but I want to actually write in the margin rather than paste anything from the body of the text.



I've also seen that it's possible to do this in such a way that the marginal comments are in small speech bubbles, which are clicked on to reveal the comments. How do I do that?

Many thanks,

Steve.
