When defining a style for a listings environment, I can set the background color by doing:

}

Apart from backgroundcolor, which other options are available? In particular, how can I set the font weight to bold?

The command texdoc has same extra options which are documented, too. Run:

texdoc texdoc

to open the documentation. Of course it is also available in the web.
