keyboard navigation in paragraph styles window

I may not need the answer to this question every day … but it's always nice to know.

I've used o,p,d to open the paragraph designer, and what I want to do next is use the Commands pull-down to add the settings of the current paragraph as a new style. Can't for the life of me find out how to get to the pull-down with the keyboard. Any ideas? Thanks in advance.
