Scrolling                                               scrolling

These commands move the contents of the window.  If the cursor position is
moved off of the window, the cursor is moved onto the window (with
'scrolloff' screen lines around it).  A page is the number of lines in the
window minus two.  The mnemonics for these commands may be a bit confusing.
Remember that the commands refer to moving the window (the part of the buffer
that you see) upwards or downwards in the buffer.  When the window moves
upwards in the buffer, the text in the window moves downwards on your screen.

1. Scrolling downwards          scroll-down
2. Scrolling upwards            scroll-up
3. Scrolling relative to cursor scroll-cursor
4. Scrolling horizontally       scroll-horizontal

==============================================================================
1. Scrolling downwards                                  scroll-down

The following commands move the edit window (the part of the buffer that you
see) downwards (this means that more lines downwards in the text buffer can be
seen):

                                                        CTRL-E
CTRL-E                  Scroll window [count] lines downwards in the buffer.
                        Mnemonic: Extra lines.

                                                        CTRL-D
CTRL-D                  Scroll window Downwards in the buffer.  The number of
                        lines comes from the 'scroll' option (default: half a
                        screen).  If [count] given, first set 'scroll' option
                        to [count].  The cursor is moved the same number of
                        lines down in the file (if possible; when lines wrap
                        and when hitting the end of the file there may be a
                        difference).  When the cursor is on the last line of
                        the buffer nothing happens and a beep is produced.
                        See also 'startofline' option.
                        {difference from vi: Vim scrolls 'scroll' screen
                        lines, instead of file lines; makes a difference when
                        lines wrap}

<S-Down>        or                              <S-Down> <kPageDown>
<PageDown>      or                              <PageDown> CTRL-F
CTRL-F                  Scroll window [count] pages Forwards (downwards) in
                        the buffer.  See also 'startofline' option.

==============================================================================
2. Scrolling upwards                                    scroll-up

The following commands move the edit window (the part of the buffer that you
see) upwards (this means that more lines upwards in the text buffer can be
seen):

                                                        CTRL-Y
CTRL-Y                  Scroll window [count] lines upwards in the buffer.

                                                        CTRL-U
CTRL-U                  Scroll window Upwards in the buffer.  The number of
                        lines comes from the 'scroll' option (default: half a
                        screen).  If [count] given, first set the 'scroll'
                        option to [count].  The cursor is moved the same
                        number of lines up in the file (if possible; when
                        lines wrap and when hitting the end of the file there
                        may be a difference).  When the cursor is on the first
                        line of the buffer nothing happens and a beep is
                        produced.  See also 'startofline' option.
                        {difference from vi: Vim scrolls 'scroll' screen
                        lines, instead of file lines; makes a difference when
                        lines wrap}

<S-Up>          or                                      <S-Up> <kPageUp>
<PageUp>        or                                      <PageUp> CTRL-B
CTRL-B                  Scroll window [count] pages Backwards (upwards) in the
                        buffer.  See also 'startofline' option.

==============================================================================
3. Scrolling relative to cursor                         scroll-cursor

The following commands reposition the edit window (the part of the buffer that
you see) while keeping the cursor on the same line:

                                                        z z<CR>
z<CR>                   Redraw, line [count] at top of window (default
                        cursor line).  Put cursor at first non-blank in the
                        line.

                                                        zt
zt                      Like "z<CR>", but leave the cursor in the same
                        column.  {not in Vi}

                                                        z.
z.                      Redraw, line [count] at center of window (default
                        cursor line).  Put cursor at first non-blank in the
                        line.

                                                        zz
zz                      Like "z.", but leave the cursor in the same column.
                        {not in Vi}

                                                        z-
z-                      Redraw, line [count] at bottom of window (default
                        cursor line).  Put cursor at first non-blank in the
                        line.

                                                        zb
zb                      Like "z-", but leave the cursor in the same column.
                        {not in Vi}

==============================================================================
4. Scrolling horizontally                               scroll-horizontal

For the following four commands the cursor follows the screen.  If the
character that the cursor is on is moved off the screen, the cursor is moved
to the closest character that is on the screen.  The value of 'sidescroll' is
not used.

z<Right>    or                                          zl z<Right>
zl                      Move the view on the text [count] characters to the
                        right, thus scroll the text [count] characters to the
                        left.  This only works when 'wrap' is off.  {not in
                        Vi}

z<Left>      or                                         zh z<Left>
zh                      Move the view on the text [count] characters to the
                        left, thus scroll the text [count] characters to the
                        right.  This only works when 'wrap' is off.  {not in
                        Vi}

                                                        zL
zL                      Move the view on the text half a screenwidth to the
                        right, thus scroll the text half a screenwidth to the
                        left.  This only works when 'wrap' is off.  {not in
                        Vi}

                                                        zH
zH                      Move the view on the text half a screenwidth to the
                        left, thus scroll the text half a screenwidth to the
                        right.  This only works when 'wrap' is off.  {not in
                        Vi}

For the following two commands the cursor is not moved in the text, only the
text scrolls on the screen.

                                                        zs
zs                      Scroll the text horizontally to position the cursor
                        at the start (left side) of the screen.  This only
                        works when 'wrap' is off.  {not in Vi}

                                                        ze
ze                      Scroll the text horizontally to position the cursor
                        at the end (right side) of the screen.  This only
                        works when 'wrap' is off.  {not in Vi}
