What SeoMoz tool am I thinking of?

A few months ago I found a tool on Moz that did keyword link research. It is not keyword analysis either. It took a word and turned it into links such as dir:cabinet. I can't find it or remember or it. Does anyone else know? (I know this description sucks, sorry about that)

Was it their Link Acquisition Assistant: http://www.seomoz.org/labs/link-finder/index.php?

That is it. Thank You
