The command \marginpar[left]{right} creates a note in the margin.
The first line will be at the same height as the line in the text where
the \marginpar occurs.
When you only specify the mandatory argument right, the text will
be placed
By issuing the command \reversemarginpar, you can force the marginal
notes to go into the opposite (inside) margin.
When you specify both arguments, left is used for the left
margin, and right is used for the right margin.
The first word will normally not be hyphenated; you can enable
hyphenation by prefixing the first word with a \hspace{0pt}
command.
