Take the tour ×  How do I change a font for a latex document?  I
am using the \documentclass{article}, which sets the document in
a serif font. I also declared \usepacke{helvet}, since thats the
font I would like to use as a sans-serif. But how do I get latex
to actually set the document in a sans-serif font?  Also, I am
using the package lslisting to format code-listings. How can I
set my document,so that all code is set in a separate font, e.g.
courier or any other typewriter font?  share|improve this
