+INTRODUCTION TO REMOTE DIRECTORY BROWSING
+
 Netrw supports the browsing of directories on remote hosts, including
-generating listing directories, entering directories, editing files
-therein, deleting files/directories, and moving (renaming) files and
-directories.
+generating listing directories, entering directories, editing files therein,
+deleting files/directories, and moving (renaming) files and directories.  The
+Netrw browser generally implements the file explorer methods but for remote
+directories, although details (such as pertinent global variable names)
+necessarily differ.
 
 To enter the netrw directory browser, simply attempt to read a "file" with a
 trailing slash and it will be interpreted as a request to list a directory:
 
 	vim [protocol]://[user@]hostname/path/

+BROWSING 						*netrw-cr*
+
 Browsing is simple: move the cursor onto a file or directory of interest.
 Hitting the <cr> (the return key) will select the file or directory.
 Directories will themselves be listed, and files will be opened using the
 protocol given in the original read request.

+REMOVING FILES OR DIRECTORIES	*netrw-delete* *netrw-remove* *netrw-D*
 
 Deleting/removing files and directories involves moving the cursor to the
-file/directory to be deleted and pressing "D".  Directories must be empty
-first before they can be successfully removed.  If the directory is a softlink
-to a directory, then netrw will make two requests to remove the directory
-before succeeding.  Netrw will ask for confirmation before doing the
-removal(s).  You may select a range of lines with the "V" command (visual

 Renaming/moving files and directories involves moving the cursor to the
 file/directory to be moved (renamed) and pressing "R".  You will then be
 queried for where you want the file/directory to be moved.  You may select a
 range of lines with the "V" command (visual selection), and then pressing "R".

+
+HIDING FILES OR DIRECTORIES		*g:netrw_a* *g:netrw_list_hide*
+
+The "a" map lets the browser ignore the g:netrw_list_hide variable.  Normally
+the g:netrw_list_hide variable holds a comma separated list of patterns which
+will be hidden (removed) from the directory listing.
+
+
+EDIT FILE OR DIRECTORY HIDING					*netrw-h*
+
+The "h" map brings up a requestor allowing the user to change the
+file/directory hiding list.
+
+
+BROWSING WITH A HORIZONTALLY SPLIT WINDOW			*netrw-o*
+
+Normally one enters a file or directory using the <cr>.  However, the "o"
+map allows one to open a new window to hold the new directory listing or
+file.  A horizontal split is used.  (also see |netrw-v|)
+
+
+SELECTING SORTING STYLE						*netrw-s*
+
+One may select the sorting style by name, time, or (file) size.  The
+"s" map allows one to circulate among the three choices; the directory
+listing will automatically be refreshed to reflect the selected style.
+
+
+REVERSING SORTING ORDER						*netrw-r*
+
+One may toggle between normal and reverse sorting order by pressing the
+"r" key.
+
+
+BROWSING WITH A VERTICALLY SPLIT WINDOW				*netrw-v*
+
+Normally one enters a file or directory using the <cr>.  However, the "v"
+map allows one to open a new window to hold the new directory listing or
+file.  A vertical split is used.  (also see |netrw-o|)
+
+
+CUSTOMIZING BROWSING WITH A USER FUNCTION			*netrw-x*
+
+One may "enter" a file with a special handler, thereby firing up a browser or
+other application, for example, on a file by hitting the "x" key.  Presumably
+one could write handlers that would start OpenOffice programs (oowriter), etc,
+based on the file's extension coupled with the user's hitting the "x" key atop
