Fish is a great shell (the best?) but its completion interface has a particular quirk that I personally don't like and would like to disable. It's expressed by this sentence in the tutorial:
Hit tab again to cycle through the possibilities.
This means that, after hitting tab to complete the longest common prefix (behavior A) and showing a menu of further entries, if you hit Tab again you start cycling through the entries (behavior B).
If there a way to disable behavior B of the Tab key, or bind it to a different key, while keeping behavior A?
