For Windows 2007, you'll go to page layout at the top, and click there. "Margins" should be one of the first drop down tabs.

The best way that I have found is to create a text box with no border in the margin, and type in it. Or are you talking about making comments in the margin? That would be done by using mark-ups.
You can change the page margins to wide or where the top left bottom and right margin is at 1 in excel easily. Just got to the top of the screen and select margin options.

Each Word document has same margins. The default margins are 1 inch at the top and bottom of the page and 1,25 inch from the left and right hand sides of the page. However, if desired, default page margins can be changed numerically.
