How to control which side a margin paragraph appears on?

Question

I would like to force a \marginpar to appear on the "wrong" side of the page (that is, in the left margin on a single-sided document).

My problem is not the slipping of \marginpars across pages addressed by marginparhack, but rather a desired to override the usual behavior at need. Nor does marginnote seem to cover my needs.

What package or cantrip can I use to easily force \marginpars to the side of my choosing?

Answer 1

From LaTeX Wiki Book:

To force margin notes onto the left side of a page use:

\marginpar[left text]{}.

There is more info on that web page :D

Answer 2

Mica's link leads to \reversemarginpar which does the trick.

Grrr...it is not as if I didn't try to google this!
