org-open-at-point
org-open-at-point is an interactive compiled Lisp function in `org.el
'.
(org-open-at-point &optional ARG REFERENCE-BUFFER)
Open link at or after point.
If there is no link at point, this function will search forward up to
the end of the current line.
Normally, files will be opened by an appropriate application. If the
optional prefix argument ARG is non-nil, Emacs will visit the file.
With a double prefix argument, try to open outside of Emacs, in the
application the system uses for this file type.
