How to highlight text in LaTeX

Add the following to your preamble:
\usepackage{color}
\newcommand{\hilight}[1]{\colorbox{yellow}{#1}}
To highlight text in the body of your document, use
\hilight{this is some highlighted text}
Voila!

Of course, you can change the color from yellow to any of the supported colors. For a list of those, check: http://en.wikibooks.org/wiki/LaTeX/Colors

UPDATE:

There is a problem with the previous method is that the color box does not wrap properly. Here's a much easier and robust way of doing this

\usepackage{soul}
To highlight text in the body of your document, use
\hl{this is some highlighted text}

  1. That doesn't quite work for me - the yellow box can't follow line wraps so the highlighted text goes off the edge of the page...

  3. Hi, just wante to point out that sometimes normal use of the soul package causes \hl to create underlines. this can be fixed by

    \usepackage{color,soul}

  4. try \hl{\emph{some text}} to see how badly it breaks.

    In this case, \hilight command works much better!

  5. This whole information is absolutely interesting. i like this blog because is easily understandable, and that is invaluable to the readers. Beyond all doubt La Tex will be very useful for everybody who want to prove it.

  9. Package soul works fine for me. I'm able to highlight text within LaTeX easily without undesired behaviour.

    However, is there an option to highlight text in one document using soul with different colours? For example line 1 with colour yellow, line 2 with colour magenta?

    Thanks for responses.

  17. To fix the emph break, dont include the initial { after emph. Then end the \hl command at the end of the text to be italicized. The ending } will end the emph as well as the \hl command. Start the \hl command again after the italicized part.
