Note about t_so and t_mr: When the termcap entry "so" is not present the
entry for "mr" is used.  And vice versa.  The same is done for "se" and "me".
If your terminal supports both inversion and standout mode, you can see two
different modes.  If you terminal supports only one of the modes, both will
look the same.

							*termcap-colors*
Note about colors: The 't_Co' option tells Vim the number of colors available.
When it is non-zero, the 't_AB' and 't_AF' options are used to set the color.
If one of these is not available, 't_Sb' and 't_Sf' are used.

							*termcap-title*
The 't_ts' and 't_fs' options are used to set the window title if the terminal
allows title setting via sending strings.  They are sent before and after the
title string, respectively.  Similar 't_IS' and 't_IE'  are used to set the
icon text.  These are Vim-internal extensions of the Unix termcap, so they
cannot be obtained from an external termcap.  However, the builtin termcap
contains suitable entries for xterm and iris-ansi, so you don't need to set
them here.
							*hpterm*
If inversion or other highlighting does not work correctly, try setting the
't_xs' option to a non-empty string.  This makes the 't_ce' code be used to
remove highlighting from a line.  This is required for "hpterm".  Setting the
'weirdinvert' option has the same effect as making 't_xs' non-empty, and vice
versa.

Some termcaps do not include an entry for 'cs' (scroll region), although the
terminal does support it.  For example: xterm on a sun.  You can use the
builtin_xterm or define t_cs yourself.  For example:
>	:set t_cs=^V^[[%i%d;%dr

Where ^V is CTRL-V and ^[ is <Esc>.

Unfortunately it is not possible to deduce from the termcap how cursor
positioning should be done when using a scrolling region: Relative to the
beginning of the screen or relative to the beginning of the scrolling region.
Most terminals use the first method.  A known exception is the MS-DOS console
(pcterm).  The 't_CS' option should be set to any string when cursor
positioning is relative to the start of the scrolling region.  It should be
set to an empty string otherwise.  It is default "yes" when 'term' is
"pcterm".

Note for xterm users: The shifted cursor keys normally don't work.  You can
	make them work with the xmodmap command and some mappings in Vim.

	Give these commands in the xterm:
		xmodmap -e "keysym Up = Up F13"
		xmodmap -e "keysym Down = Down F16"
		xmodmap -e "keysym Left = Left F18"
		xmodmap -e "keysym Right = Right F19"

	And use these mappings in Vim:
		:map <t_F3> <S-Up>
		:map! <t_F3> <S-Up>
		:map <t_F6> <S-Down>
		:map! <t_F6> <S-Down>
		:map <t_F8> <S-Left>
		:map! <t_F8> <S-Left>
		:map <t_F9> <S-Right>
		:map! <t_F9> <S-Right>

Instead of, say, <S-Up> you can use any other command that you want to use the
shift-cursor-up key for.  (Note: To help people that have a Sun keyboard with
left side keys F14 is not used because it is confused with the undo key; F15
is not used, because it does a window-to-front; F17 is not used, because it
closes the window.  On other systems you can probably use them)

==============================================================================
3. Window size						*window-size*

[This is about the size of the whole window Vim is using, not a window that is
created with the :split command]

If you are running Vim on an Amiga and the terminal name is "amiga" or
"builtin_amiga", the amiga-specific window resizing will be enabled.  On Unix
systems three methods are tried to get the window size:

- an ioctl call (TIOCGSIZE or TIOCGWINSZ, depends on your system)
- the environment variables "LINES" and "COLUMNS"
- from the termcap entries "li" and "co"

If everything fails a default size of 24 lines and 80 columns is assumed.  If
a window-resize signal is received the size will be set again.  If the window
size is wrong you can use the 'lines' and 'columns' options to set the
correct values.

One command can be used to set the screen size:

							*:mod* *:mode*
:mod[e] [mode]

Without argument this only detects the screen size and redraws the screen.
With MS-DOS it is possible to switch screen mode.  [mode] can be one of these
values:
	"bw40"		40 columns black&white
	"c40"		40 columns color
	"bw80"		80 columns black&white
	"c80"		80 columns color (most people use this)
	"mono"		80 columns monochrome
	"c4350"		43 or 50 lines EGA/VGA mode
	number		mode number to use, depends on your video card

==============================================================================
4. Slow and fast terminals			*slow-fast-terminal*
						*slow-terminal*

If you have a fast terminal you may like to set the 'ruler' option.  The
cursor position is shown in the status line.  If you are using horizontal
scrolling ('wrap' option off) consider setting 'sidescroll' to a small
number.

If you have a slow terminal you may want to reset the 'showcmd' option.
The command characters will not be shown in the status line.  If the terminal
scrolls very slowly, set the 'scrolljump' to 5 or so.  If the cursor is moved
off the screen (e.g., with "j") Vim will scroll 5 lines at a time.  Another
possibility is to reduce the number of lines that Vim uses with the command
"z{height}<CR>".

If the characters from the terminal are arriving with more than 1 second
between them you might want to set the 'timeout' and/or 'ttimeout' option.
See the "Options" chapter |options|.

If your terminal does not support a scrolling region, but it does support
insert/delete line commands, scrolling with multiple windows may make the
lines jump up and down.  If you don't want this set the 'ttyfast' option.
This will redraw the window instead of scroll it.

If your terminal scrolls very slowly, but redrawing is not slow, set the
'ttyscroll' option to a small number, e.g., 3.  This will make Vim redraw the
screen instead of scrolling, when there are more than 3 lines to be scrolled.

If you are using Vim over a slow serial line, you might want to try running
Vim inside the "screen" program.  Screen will optimize the terminal I/O quite
a bit.

If you are testing termcap options, but you cannot see what is happening,
you might want to set the 'writedelay' option.  When non-zero, one character
