fix action names in the interface

Found a small problem, which is fortunate, because now I can make a pull request out of it.

But as I’m sure you know, the entire plug-in is new. I was hoping to have it out prior to 10.9, but that clearly didn’t happen.

After reading [the review][1], I’m not sure how this will play with colored labels, but it should work anyway.
