How to view move_base/action_topics ?

Hello,

I have just started working with the ROS navigation stack, specifically the movebase package. The /movebase node publishes lots of topics, one of which is movebase/actiontopics. As opposed to every other topic i have seen this one is missing the initial slash, so it is "movebase/actiontopics" as opposed to "/movebase/actiontopics". I cannot echo any information from this topic either and i'm not sure why.

My guesses are that it is a custom topic or has something to do with the missing /.

I have tried rostopic list but the topic in question does not show up. I have also tried rostopic echo move_base/action_topics but nothing is displayed.
