How do I close a path?

I created a path, but I can’t figure out how to close it! I know you can press “C” in 2.49, but this is Blender 2.5 BETA, and it’s not working. Please help!

I don’t have blender in front of me but I believe it is either Alt+C or Ctrl+C.
As with most queries like this, just look in the 3d view header menu, this case under Curves as I know it tells you there, along with the key shortcut or Space bar search.
