Inserts a marginal note on odd pages. This is required for RTF generation since it is impossible for Tex2RTF to know in advance which side of paper the marginal note will fall upon, and the text has to be positioned using absolute dimensions.
Also, even if one-sided output is required, this command should be used instead of \marginpar because the LaTeX command allows it to be used just before a paragraph. Normally, if this were done, the marginal note would not be aligned with the paragraph succeeding it. For example:
\marginparodd{{\it Note:} if nothing happens, perhaps you have not plugged your computer in at the mains.}% To start using your computer, push the Power button and wait for text to appear on the screen.Note the percent sign after the \marginparodd command: without it, LaTeX refuses to believe that the following text is part of the same paragraph, and will print the note at the wrong place.
You should use \textwidth to allow space for marginal notes, and also \marginparwidth to specify the size of the marginal note.
In WinHelp, HTML and wxHelp, marginal notes are treated as normal text delineated with horizontal rules above and below.
