Geeky question regarding friends pages

[pegkerr]

I know that you can set your friends page to display without communities by adding

?show=p

to the end of the URL, i.e.,

http://pegkerr.livejournal.com/friends/

becomes

http://pegkerr.livejournal.com/friends/?show=p

My question is, is there a URL string which shows nothing but the communities on your friends page?

Edited to add: zedmeister had the answer: it's http://pegkerr.livejournal.com/friends/?show=c

Thanks, zedmeister!

And heinous_bitca mentions that there is also ?show=Y to show feeds.
