The file's suffix is used by these various approaches to determine an
appropriate application to use to "handle" these files. Such things as
OpenOffice (*.sfx), visualization (*.jpg, *.gif, etc), and PostScript (*.ps,
*.eps) can be handled.
The gx mapping extends to all buffers; apply "gx" while atop a word and netrw
will apply a special handler to it (like "x" works when in a netrw buffer).

When |g:netrw_browsex_viewer| exists and is "-", then netrw will attempt to
handle the special file with a vim function. The "x" map applies a function
to a file, based on its extension. Of course, the handler function must exist
for it to be called!

Ex. mypgm.html x -> NFH_html("scp://user@host/some/path/mypgm.html")
< Users may write their own netrw File Handler functions to
support more suffixes with special handling. See

file handler functions. As an example: >
" NFH_suffix(filename)

<
These functions need to be defined in some file in your .vim/plugin
(vimfiles\plugin) directory. Vim's function names may not have punctuation
characters (except for the underscore) in them. To support suffices that
contain such characters, netrw will first convert the suffix using the
following table: >
@ -> AT ! -> EXCLAMATION % -> PERCENT
: -> COLON = -> EQUAL ? -> QUESTION
, -> COMMA - -> MINUS ; -> SEMICOLON
$ -> DOLLAR + -> PLUS ~ -> TILDE
