I'm sorry, I forgot to mention that I know I can do highlighting with
Insert->Program Listing. But I would like coloured syntax.
The listings package uses multiple keywords to control various colors
(background, keywords, comments, ...), which you will need to set. So:
1. Add something to load your favorite color package (most likely
color.sty or xcolor.sty) to the preamble. LyX (at least as of version
1.5.6) does not do this automatically unless something else in the
document triggers it. For instance, you can say
\usepackage[svgnames]{xcolor}, which gives you access to the svgnames
palette of colors.
2. Right click the gray (or is it 'gray' for a color and 'grey' for a
colour?) handle of the listings inset. Select the language on the Main
Settings tab, then switch to the Advanced tab. You can type a question
mark (?) in the box to get a list of known parameters. Type in your
choices in the format key=value. You can find the relevant parameters
in the documentation for the listings package. LyX is fairly smart
about adding braces as needed if you just type one entry per line, and
as you type parameter names it will show you a list of possible
completions on the left (but, AFAIK, won't auto-complete for you, at
least as of version 1.5.6). For example (using svgnames)
commentstyle=\color{DarkGreen}
keywordstyle=\color(Blue}
does exactly what you would expect. Note that you can fiddle with other
style attributes (such as putting keywords in italics) as well.
