I would have started this paragraph with: "With or without ido
keybindings".  Ido keybindings only adds cycling, it doesn't mess with
the display.  It is not clear to me how "Without ido keybindings" makes
it "useful to see all completions" .

If you want bigger real-estate you can tweak the icomplete-separator
option.
