Show the documentation for the current commandline parameters

Question

When using fish I often struggle where I hit tab to open up the command line completion. But then when I type the first letter of the completion the menu closes. Can I keep it open and have it select / reduce the options so that I don't need to delete the letter, hit tab again, etc to view what my letter stood for?

Answer 1

You might be looking for the completions search feature, allowing you to reduce the options. It looks like so:

You can open the search field when the completion pager is already shown via Control-S. Alternatively you can trigger tab completion with the search field focused via shift-tab. These keys can be changed using bind if you prefer.
