Thanks, Ben… Yes I’ve got a dotfile repo but that wasn’t it. I finally figured out that I had accidentally put this feature file in a directory parallel to ./features, rather than under it – dang!
Anyway, it’s fixed and Time Pope (where I did join a ticket with other folks having a similar problem) and he was very helpful. I also learned, belatedly, that he had changed the mapping for the feature => step definition ‘jump’ key from Ctrl-] to ]Ctrl-D to avoid conflicts with the built-in vim mapping.
