How to load a saved playlist ?

I've got a saved playlist in ~/Music/playlist.m3u that I want to load. It shows up in the directory list on the left hand side, but
when I select it, or press return/enter when it is selected, the playlist does not appear on the right hand side. Am I doing something wrong ? I don't see a "load playlist" type of command in the help. Or did I just miss it ?

Pressing enter works for me. Did you clear your active playlist before doing that? There is a warning message about it at the bottom if you didn't.

That worked. Thanks.
