Activating Eclipse Django Editor on OS X

I installed a plugin for Eclip开发者_开发问答se called Django Editor. I can't figure out how to use it. The editor is not in my list of editors so I cannot do "Open with Django Editor" on a file nor associate a file extension with it. It appears nowhere in my preferences. How can I activate this editor?

I am running Mac OS X 10.5.8 and Eclipse 3.5.2 Galileo.

Assuming you installed it properly, it should show up when you edit .html files as a context item.alt text http://xs.to/image-0DAF_4BE630E5.jpg
