The manual describes the "internal horizontal scrolling" (for lack of
better description)  that occurs in graphics mode and terminal mode but not
one based on horizontal scroll bar and does not mention
`horizontal-scroll-bar-mode'.

 horizontal-scroll-bar-mode handles the horizontal scroll-bar globally.  But I have
forgotten how to handle the horizontal scroll-bar per window.  Or is it per frame ?

The answers are in the manual:

     To toggle the use of horizontal scroll bars, type ‘M-x
  horizontal-scroll-bar-mode’.  This command applies to all frames,
  including frames yet to be created.  To toggle horizontal scroll bars
  for just the selected frame, use the command ‘M-x
  toggle-horizontal-scroll-bar’.

Yes per-frame but not per-window.  I have no idea whether vertical scrollbar
is also per-frame.

What would be the commands to scroll vertically per-window and per-buffer ?

C-h f toggle-horizontal-scroll-bar 

gives

"With ARG, turn vertical scroll bars on if and only if ARG is positive."

The use of the word "vertical" is wrong.

The answer is again in the manual:

     To toggle the use of vertical scroll bars, type ‘M-x
  scroll-bar-mode’.  This command applies to all frames, including frames
  yet to be created.  To toggle vertical scroll bars for just the selected
  frame, use the command ‘M-x toggle-scroll-bar’.

If this activates vertical scroll bar of a window, how does one deactivate it ?

(set-window-scroll-bars (selected-window) nil 'right)

Please read the ELisp manual, where this function is described.  The
answers are all there.

After playing with for some time, I am able to use it properly.  
Many thanks Eli.
