:[N]sp[lit] [++opt] [+cmd] {file} *:split_f*

Create a new window and start editing file {file} in it. This

behaves like a ":split" first, and then an ":e" command.

If [+cmd] is given, execute the command when the file hasbeen

loaded |+cmd|.

Also see |++opt|.

Make new window N high (default is to use half theexisting

height).  Reduces the current window heightto create room

(and others, if the 'equalalways' option is set).

:[N]vs[plit] [++opt] [+cmd] [file] *:vs* *:vsplit*

Like |:split|, but split vertically.  Thewindows will be

spread out horizontally if

1. a width was not specified,

2. 'equalalways' is set,

3. 'eadirection' isn't "ver", and

4. one of the other windows is wider than the current ornew

  window.

Note: In other places CTRL-Q does the same as CTRL-V, buthere

it doesn't!

==============================================================================

6. Window resizing *window-resize*

*CTRL-W_=*

CTRL-W = Make all windows (almost) equally high and wide, butuse

'winheight' and 'winwidth' for the current window.

Windows with 'winfixheight' set keep their height andwindows

with 'winfixwidth' set keep their width.

:res[ize] -N *:res* *:resize* *CTRL-W_-*

CTRL-W - Decrease current window height by N (default1).

If used after |:vertical|: decrease width by N.

:res[ize] +N *CTRL-W_+*

CTRL-W + Increase current window height by N (default1).

If used after |:vertical|: increase width by N.

:res[ize] [N]

CTRL-W CTRL-_ *CTRL-W_CTRL-_* *CTRL-W__*

CTRL-W _ Set current window height to N (default: highestpossible).

z{nr} Set current window height to {nr}.

*CTRL-W_<*

CTRL-W <<span class="Apple-tab-span"style="white-space:pre"> Decrease current window width by N(default 1).

*CTRL-W_>*

CTRL-W > Increase current window width by N (default1).

:vertical res[ize] [N] *:vertical-resize* *CTRL-W_bar*

CTRL-W | Set current window width to N (default: widestpossible).

You can also resize a window by dragging a status line up ordown with the

mouse.  Or by dragging a vertical separatorline left or right.  This only

works if the version of Vim that is being used supports themouse and the

'mouse' option has been set to enable it.

The option 'winheight' ('wh') is used to set the minimalwindow height of the

current window.  This option is used eachtime another window becomes the

current window.  If the option is '0', it isdisabled.  Set 'winheight' to a

very large value, e.g., '9999', to make the current windowalways fill all

available space.  Set it to a reasonablevalue, e.g., '10', to make editing in

the current window comfortable.

The equivalent 'winwidth' ('wiw') option is used to set theminimal width of

the current window.

When the option 'equalalways' ('ea') is set, all the windowsare automatically

made the same size after splitting or closing a window. If you don't set this

option, splitting a window will reduce the size of the currentwindow and

leave the other windows the same.  Whenclosing a window, the extra lines are

given to the window above it.

The 'eadirection' option limits the direction in which the'equalalways'

option is applied.  The default "both"resizes in both directions.  When the

value is "ver" only the heights of windows are equalized. Use this when you

have manually resized a vertically split window and want tokeep this width.

Likewise, "hor" causes only the widths of windows to beequalized.

The option 'cmdheight' ('ch') is used to set the height of thecommand-line.

If you are annoyed by the |hit-enter| prompt for longmessages, set this

option to 2 or 3.

If there is only one window, resizing that window will alsochange the command

line height.  If there are several windows,resizing the current window will

also change the height of the window below it (and sometimesthe window above

it).

The minimal height and width of a window is set with'winminheight' and

'winminwidth'.  These are hard values, awindow will never become smaller.
