- ``repaint`` reexecutes the prompt functions and redraws the prompt. Multiple successive repaints are coalesced.
- ``repaint-mode`` reexecutes the fish_mode_prompt function and redraws the prompt. This is useful for vi-mode. If no fish_mode_prompt exists, it acts like a normal repaint.
- ``repaint-mode`` reexecutes the :ref:`fish_mode_prompt <cmd-fish_mode_prompt>` and redraws the prompt. This is useful for vi-mode. If no ``fish_mode_prompt`` exists, it acts like a normal repaint.
- ``self-insert``, inserts the matching sequence into the command line

The ``fish_mode_prompt`` function outputs the mode indicator for use in vi-mode.
The default ``fish_mode_prompt`` function will output indicators about the current Vi editor mode displayed to the left of the regular prompt. Define your own function to customize the appearance of the mode indicator. You can also define an empty ``fish_mode_prompt`` function to remove the Vi mode indicators. The ``$fish_bind_mode variable`` can be used to determine the current mode. It
will be one of ``default``, ``insert``, ``replace_one``, or ``visual``.

fish_mode_prompt will be executed when the vi mode changes. If it produces any output, it is displayed and used. If it does not, the other prompt functions (:ref:`fish_prompt <cmd-fish_prompt>` and :ref:`fish_right_prompt <cmd-fish_right_prompt>`) will be executed as well in case they contain a mode display.
You can also define an empty ``fish_mode_prompt`` function to remove the Vi mode indicators::
function fish_mode_prompt; end
