input mode, the cursor moves to the matching open parenthesis or brace. It<br />

stays there for about one second and then moves back to where you were.<br />

This lets you note the relationship between opening and closing<br />

parentheses/braces.<br />

The default is noshowmatch.<br />

showmode<br />

When this option is on, vi displays an indicator in the bottom right-hand<br />

corner of the screen if you are in Insert/Open/Change/Replace mode. If no<br />

indicator is displayed, you are in <strong>Command</strong> mode.<br />

The default is noshowmode.<br />

tabstop<br />

Tab stops for screen display in vi mode are set to multiples of this number.<br />

The default is tabstop=8.<br />

taglength, tl<br />

If this variable is nonzero, tags are only compared for this number of<br />

characters.<br />

The default is taglength=0.<br />

tags The value of this variable should be a list of file names separated by a<br />

backslash (\) followed by a space. If there is no backslash before the<br />

space, vi treats the second and subsequent tags as part of an<br />

option=value combination. For example:<br />

set tags=file1\ file2\ file3\<br />

These are used by the tag ex command and the Ctrl-] vi command. The<br />

files are typically created with the ctags program.<br />

The default is tags=tags.<br />

term The value of this variable is the terminal type. The TERM environment<br />

variable specifies this variable’s default value.<br />

terse If this option is on, messages are displayed in a very abbreviated form. The<br />

default is noterse.<br />

warn When this option is on, commands with an exclamation mark (!) print a<br />

warning message if the current file has been modified. No message is<br />

printed if this option is off.<br />

The default is warn.<br />

window This variable gives the number of text lines available in vi mode or the<br />

default number of lines to display for the command.<br />

The default is given by the –w option. If it is not specified with the –w<br />

option, its value defaults to the environment variable LINES or the value<br />

found in the terminfo database for TERM.<br />

wrapmargin wm<br />

If this variable is nonzero in vi insert mode, when a line reaches this<br />

number of characters from the right of the screen, the current word moves<br />

down to the next line automatically; you don’t have to press ENTER.<br />

The default is wramargin=0.<br />
