silenced.
	You can also make it flash by using 'visualbell'.

	item	    meaning when present	~
	all	    All events.
	backspace   When hitting <BS> or <Del> and deleting results in an
		    error.
	cursor	    Fail to move around using the cursor keys or
		    <PageUp>/<PageDown> in |Insert-mode|.
	complete    Error occurred when using |i_CTRL-X_CTRL-K| or
		    |i_CTRL-X_CTRL-T|.
	copy	    Cannot copy char from insert mode using |i_CTRL-Y| or
		    |i_CTRL-E|.
	ctrlg	    Unknown Char after <C-G> in Insert mode.
	error	    Other Error occurred (e.g. try to join last line)
		    (mostly used in |Normal-mode| or |Cmdline-mode|).
	esc	    hitting <Esc> in |Normal-mode|.

	This is most useful to fine tune when in Insert mode the bell should
	be rung. For Normal mode and Ex commands, the bell is often rung to
	indicate that an error occurred. It can be silenced by adding the
	"error" keyword.

				*'binary'* *'bin'* *'nobinary'* *'nobin'*
'binary' 'bin'		boolean	(default off)
			local to buffer
	This option should be set before editing a binary file.  You can also
	use the |-b| Vim argument.  When this option is switched on a few
	options will be changed (also when it already was on):
		'textwidth'  will be set to 0
		'wrapmargin' will be set to 0
		'modeline'   will be off
		'expandtab'  will be off
	Also, 'fileformat' and 'fileformats' options will not be used, the
	file is read and written like 'fileformat' was "unix" (a single <NL>
	separates lines).
	The 'fileencoding' and 'fileencodings' options will not be used, the
	file is read without conversion.
	NOTE: When you start editing a(nother) file while the 'bin' option is
	on, settings from autocommands may change the settings again (e.g.,
	'textwidth'), causing trouble when editing.  You might want to set
	'bin' again when the file has been loaded.
	The previous values of these options are remembered and restored when
	'bin' is switched from on to off.  Each buffer has its own set of
	saved option values.
	To edit a file with 'binary' set you can use the |++bin| argument.
	This avoids you have to do ":set bin", which would have effect for all
	files you edit.
	When writing a file the <EOL> for the last line is only written if
	there was one in the original file (normally Vim appends an <EOL> to
	the last line if there is none; this would make the file longer).  See
	the 'endofline' option.

						*'bomb'* *'nobomb'*
'bomb'			boolean	(default off)
			local to buffer
	When writing a file and the following conditions are met, a BOM (Byte
	Order Mark) is prepended to the file:
	- this option is on
	- the 'binary' option is off
	- 'fileencoding' is "utf-8", "ucs-2", "ucs-4" or one of the little/big
	  endian variants.
	Some applications use the BOM to recognize the encoding of the file.
	Often used for UCS-2 files on MS-Windows.  For other applications it
	causes trouble, for example: "cat file1 file2" makes the BOM of file2
	appear halfway through the resulting file.  Gcc doesn't accept a BOM.
	When Vim reads a file and 'fileencodings' starts with "ucs-bom", a
	check for the presence of the BOM is done and 'bomb' set accordingly.
	Unless 'binary' is set, it is removed from the first line, so that you
	don't see it when editing.  When you don't change the options, the BOM
	will be restored when writing the file.

						*'breakat'* *'brk'*
'breakat' 'brk'		string	(default " ^I!@*-+;:,./?")
			global
	This option lets you choose which characters might cause a line
	break if 'linebreak' is on.  Only
