Which new shortcodes does catWalker add to WordPress?

The plugin catWalker added 3 new shortcodes when it was installed with WP-CLI in our WordPress test environment.

ShortCode		Known Plugin or Theme conflicts
[categories]		The categories shortcode has potential conflicts with at least 4 other plugins or themes.
[category-posts]		The category-posts shortcode doesn't have any known conflicts with other themes or plugins.
[crosscat]		The crosscat shortcode doesn't have any known conflicts with other themes or plugins.

Note: We have not yet checked to see if these shortcodes work as expected in pages, posts, sidebar widgets, or when set as the page title, in content, in the excert, in menus or anywhere else within a WordPress installation. A shortcode could produce errors due to parameters added when it is used, or if the plugin is updated and the format of the shortcode has changed.
