In fish, I have an abbreviation that automatically expands double dots into ../ so that you can just spam double dots and visually see how far you're going.

  function append-slash-to-double-dot -d 'expand .. to ../'
   # Get commandline up to cursor
   set -l cmd (commandline --cut-at-cursor)
  
   # Match last line
   switch $cmd[-1]
   case '*.'
    commandline --insert './'
   case '*'
    commandline --insert '.'
   end
  end
