"Alist mapping major modes to their `counsel-outline' settings.
Each entry is a pair (MAJOR-MODE . PLIST). `counsel-outline'
checks whether an entry exists for the current buffer's
MAJOR-MODE and, if so, loads the settings specified by PLIST
instead of the default settings. The following settings are
recognized:
- `:outline-regexp' is a regexp to match the beginning of an
outline heading. It is only checked at the start of a line and
so need not start with \"^\".
Defaults to the value of the variable `outline-regexp'.
- `:outline-level' is a function of no arguments which computes
the level of an outline heading. It is called with point at
the beginning of `outline-regexp' and with the match data
corresponding to `outline-regexp'.
Defaults to the value of the variable `outline-level'.
- `:outline-title' is a function of no arguments which returns
the title of an outline heading. It is called with point at
the end of `outline-regexp' and with the match data
corresponding to `outline-regexp'.
Defaults to the function `counsel-outline-title'.
- `:action' is a function of one argument, the selected outline
heading to jump to. This setting corresponds directly to its
eponymous `ivy-read' keyword, as used by `counsel-outline', so
the type of the function's argument depends on the value
returned by `counsel-outline-candidates'.
Defaults to the function `counsel-outline-action'.
- `:history' is a history list, usually a symbol representing a
history list variable. It corresponds directly to its
eponymous `ivy-read' keyword, as used by `counsel-outline'.
Defaults to the symbol `counsel-outline-history'.
- `:caller' is a symbol to uniquely identify the caller to
`ivy-read'. It corresponds directly to its eponymous
`ivy-read' keyword, as used by `counsel-outline'.
Defaults to the symbol `counsel-outline'.
- `:display-style' overrides the variable
`counsel-outline-display-style'.
- `:path-separator' overrides the variable
`counsel-outline-path-separator'.
- `:face-style' overrides the variable
`counsel-outline-face-style'.
- `:custom-faces' overrides the variable
`counsel-outline-custom-faces'.")

If `verbatim', the faces used in the buffer are applied. For
simple headlines in `org-mode' buffers, this is usually the same

buffer has been completely fontified. If your buffer exceeds a
certain size, headlines are styled lazily depending on which

well. If your headlines contain parts which are fontified
differently than the headline itself (e.g. TODO keywords, tags,
links) and you want these parts to be styled properly, verbatim
is the way to go; otherwise you are probably better off using the
`org' setting instead.
If `custom', the faces defined in `counsel-outline-custom-faces'
are applied. Note that no cycling is performed, so if there is
