;;; Commentary:
;;
;; Implicit button types (ibtypes) in this file are defined in increasing
;; order of priority within this file (last one is highest priority).
;;
;; To return a list of the implicit button types in priority order (highest
;; to lowest), evaluate:
;;
;; (symset:get 'ibtypes 'symbols)
;;
;; If you need to reset the priorities of all ibtypes, evaluate:
;;
;; (symset:clear 'ibtypes)
;;
;; and then reload this file.
;;
;; To get a list of all loaded action types, evaluate:
;;
;; (symset:get 'actypes 'symbols)

"Make a valid pathname at point display the path entry.
If instead is a PATH-style variable name, .e.g. MANPATH, will prompt
with completion for one of the paths and will then display that. If
it is the colon or semicolon-separated string of paths value from a
PATH-style variable, the path at point is used; empty paths, e.g. ::
represent the current directory, '.'.
Also works for delimited and non-delimited remote pathnames,
recursive \\='ls' listings, Texinfo @file{} entries, and hash-style
link references to HTML, XML, SGML, Markdown or Emacs outline
headings, shell script comments, and MSWindows paths (see
\"${hyperb:dir}/DEMO#POSIX and MSWindows Paths\" for details).
Emacs Lisp library files (filenames without any directory
component that end in .el, .elc or .eln) are looked up using the
`load-path' directory list.
The pathname may contain references to Emacs Lisp variables or
shell environment variables using the syntax, \"${variable-name}\".
