# Setting a New Command (or is it an Environment?)

Here's a small example of what I have to use. I have to reset the length everytime I use \marginnote because it restarts indenting and reformats the skip to 0.

\marginnote{\normalsize Some text goes here}
\setlength{\parindent}{0in}
\setlength{\parskip}{0.15in}

What I would like to be able to do is redefine this behaviour so I don't have to type so much junk (and keep my tex/Sweave document cleaner)

\somecommand Some text goes here

Is there a way to get it to do so?

Why does \marginnote reset the lengths in the first place? – Werner Mar 5 '12 at 18:23
No idea, and I don't understand latex enough to figure it out* – Brandon Bertelsen Mar 5 '12 at 18:24
The grouping I suggest in my answer should work to keep the length modification to "within" \somecommand. – Werner Mar 5 '12 at 18:25
That it does - thanks! – Brandon Bertelsen Mar 5 '12 at 18:29

You could use a grouping structure to localise any changes made by \marginnote:

\newcommand{\somecommand}[1]{% \somecommand{<text>}
\begingroup
\marginnote{\normalsize #1}%
\endgroup
}

You would then use

\somecommand{Some text goes here.}

Perfect, I just added my \setlength's after \marginnote and it works as expected. – Brandon Bertelsen Mar 5 '12 at 18:29
