The case refers to the documentation page which appears in my local Unity installation here:
file:///Applications/Unity/Unity.app/Contents/Documentation/html/en/Manual/SL-Pass.html

Some (or possibly all) of the commands under the "Render Setup" section have their own wiki pages, and it would be excellent to include links here. Currently the pages for these commands can be reached via the navigation tree in the browser sidebar, but if that portion of the tree is collapsed then it is not obvious that more information is readily available.

For example, where the Blend command is defined it would be informative to include a hyperlink to the page which describes the blend operations that are available:
file:///Applications/Unity/Unity.app/Contents/Documentation/html/en/Manual/SL-Blend.html
