 PREDEFINED VIM VARIABLES			*vim-variable* *v:var* *v:*
 								*E963*
-Some variables can be set by the user, but the type cannot be changed.
-
-					*v:argv* *argv-variable*
-v:argv		The command line arguments Vim was invoked with.  This is a
-		list of strings.  The first item is the Vim command.
-		See |v:progpath| for the command with full path.
-
-					*v:char* *char-variable*
-v:char		Argument for evaluating 'formatexpr' and used for the typed
-		character when using <expr> in an abbreviation |:map-<expr>|.
-		It is also used by the |InsertCharPre| and |InsertEnter| events.
-
-			*v:charconvert_from* *charconvert_from-variable*
-v:charconvert_from
-		The name of the character encoding of a file to be converted.
-		Only valid while evaluating the 'charconvert' option.
-
-			*v:charconvert_to* *charconvert_to-variable*
-v:charconvert_to
-		The name of the character encoding of a file after conversion.
-		Only valid while evaluating the 'charconvert' option.
-
-					*v:cmdarg* *cmdarg-variable*
-v:cmdarg
-		The extra arguments ("++p", "++enc=", "++ff=") given to a file
-		read/write command.  This is set before an autocommand event
-		for a file read/write command is triggered.  There is a
-		leading space to make it possible to append this variable
-		directly after the read/write command. Note: "+cmd" isn't
-		included here, because it will be executed anyway.
-
-						*v:collate* *collate-variable*
-v:collate	The current locale setting for collation order of the runtime
-		environment.  This allows Vim scripts to be aware of the
-		current locale encoding.  Technical: it's the value of
-		LC_COLLATE.  When not using a locale the value is "C".
-		This variable can not be set directly, use the |:language|
-		command.
-		See |multi-lang|.
-
-					*v:cmdbang* *cmdbang-variable*
-v:cmdbang	Set like v:cmdarg for a file read/write command.  When a "!"
-		was used the value is 1, otherwise it is 0.  Note that this
-		can only be used in autocommands.  For user commands |<bang>|
-		can be used.
-
-				*v:completed_item* *completed_item-variable*
-v:completed_item
-		Dictionary containing the most recent |complete-items| after
-		|CompleteDone|.  Empty if the completion failed, or after
-		leaving and re-entering insert mode.
-		Note: Plugins can modify the value to emulate the builtin
-		|CompleteDone| event behavior.
-
-					*v:count* *count-variable*
-v:count		The count given for the last Normal mode command.  Can be used
-		to get the count before a mapping.  Read-only.  Example: >
-	:map _x :<C-U>echo "the count is " .. v:count<CR>
-<		Note: The <C-U> is required to remove the line range that you
-		get when typing ':' after a count.
-		When there are two counts, as in "3d2w", they are multiplied,
-		just like what happens in the command, "d6w" for the example.
-		Also used for evaluating the 'formatexpr' option.
-
-					*v:count1* *count1-variable*
-v:count1	Just like "v:count", but defaults to one when no count is
-		used.
-
-						*v:ctype* *ctype-variable*
-v:ctype		The current locale setting for characters of the runtime
-		environment.  This allows Vim scripts to be aware of the
-		current locale encoding.  Technical: it's the value of
-		LC_CTYPE.  When not using a locale the value is "C".
-		This variable can not be set directly, use the |:language|
-		command.
-		See |multi-lang|.
-
-					*v:dying* *dying-variable*
-v:dying		Normally zero.  When a deadly signal is caught it's set to
-		one.  When multiple signals are caught the number increases.
-		Can be used in an autocommand to check if Vim didn't
-		terminate normally.
-		Example: >
-	:au VimLeave * if v:dying | echo "\nAAAAaaaarrrggghhhh!!!\n" | endif
-<		Note: if another deadly signal is caught when v:dying is one,
-		VimLeave autocommands will not be executed.
-
-					*v:exiting* *exiting-variable*
-v:exiting	Exit code, or |v:null| before invoking the |VimLeavePre|
-		and |VimLeave| autocmds.  See |:q|, |:x| and |:cquit|.
-		Example: >
-			:au VimLeave * echo "Exit value is " .. v:exiting
-<
-					*v:echospace* *echospace-variable*
-v:echospace	Number of screen cells that can be used for an `:echo` message
-		in the last screen line before causing the |hit-enter-prompt|.
-		Depends on 'showcmd', 'ruler' and 'columns'.  You need to
-		check 'cmdheight' for whether there are full-width lines
-		available above the last line.
-
-					*v:errmsg* *errmsg-variable*
-v:errmsg	Last given error message.
-		Modifiable (can be set).
-		Example: >
-	:let v:errmsg = ""
-	:silent! next
-	:if v:errmsg != ""
-	:  ... handle error
-<
-				*v:errors* *errors-variable* *assert-return*
-v:errors	Errors found by assert functions, such as |assert_true()|.
-		This is a list of strings.
-		The assert functions append an item when an assert fails.
-		The return value indicates this: a one is returned if an item
-		was added to v:errors, otherwise zero is returned.
-		To remove old results make it empty: >
-	:let v:errors = []
-<		If v:errors is set to anything but a list it is made an empty
-		list by the assert function.
-
-					*v:event* *event-variable*
-v:event		Dictionary of event data for the current |autocommand|.  Valid
-		only during the event lifetime; storing or passing v:event is
-		invalid!  Copy it instead: >
-			au TextYankPost * let g:foo = deepcopy(v:event)
-<		Keys vary by event; see the documentation for the specific
-		event, e.g. |DirChanged| or |TextYankPost|.

-					by the |:yank| Ex command then
-					`v:event.operator` is "y".
-			regcontents	Text stored in the register as a
-					|readfile()|-style list of lines.
-			regname		Requested register (e.g "x" for "xyy)
-					or the empty string for an unnamed
-					operation.
-			regtype		Type of register as returned by
-					|getregtype()|.
-			visual		Selection is visual (as opposed to,
-					e.g., via motion).

-					|CompleteChanged|.
-			scrollbar	Is |v:true| if popup menu have scrollbar, or
-					|v:false| if not.
-			changed_window	Is |v:true| if the event fired while
-					changing window (or tab) on |DirChanged|.
-			status		Job status or exit code, -1 means "unknown". |TermClose|
-
-					*v:exception* *exception-variable*
-v:exception	The value of the exception most recently caught and not
-		finished.  See also |v:throwpoint| and |throw-variables|.

-	:endtry
-<		Output: "caught oops".
-
-					*v:false* *false-variable*
-v:false		Special value used to put "false" in JSON and msgpack.  See
-		|json_encode()|.  This value is converted to "v:false" when used
-		as a String (e.g. in |expr5| with string concatenation
-		operator) and to zero when used as a Number (e.g. in |expr5|
-		or |expr7| when used with numeric operators). Read-only.
-
-					*v:fcs_reason* *fcs_reason-variable*
-v:fcs_reason	The reason why the |FileChangedShell| event was triggered.
-		Can be used in an autocommand to decide what to do and/or what

-
-					*v:fcs_choice* *fcs_choice-variable*

-		triggered.  Can be used in an autocommand to tell Vim what to
-		do with the affected buffer:
-			reload		Reload the buffer (does not work if
-					the file was deleted).
-			edit		Reload the buffer and detect the
-					values for options such as
-					'fileformat', 'fileencoding', 'binary'
-					(does not work if the file was
-					deleted).
-			ask		Ask the user what to do, as if there
-					was no autocommand.  Except that when
-					only the timestamp changed nothing
-					will happen.
-			<empty>		Nothing, the autocommand should do
-					everything that needs to be done.

-		file and different from v:fname_in.
-
-					*v:fname_new* *fname_new-variable*

-<		Note that the value is restored when returning from a
-		function. |function-search-undo|.
-

-		operator) and to zero when used as a Number (e.g. in |expr5|
-		or |expr7| when used with numeric operators). Read-only.
-		In some places `v:null` can be used for a List, Dict, etc.

-		character except for commands starting with <g> or <z>,
-		in which case it is two characters.  Best used alongside
-		|v:prevcount| and |v:register|.  Useful if you want to cancel
-		Operator-pending mode and then use the operator, e.g.: >
-			:omap O <Esc>:call MyMotion(v:operator)<CR>

+
+
+Predefined variables                                             *vvars*
+
+Some variables can be set by the user, but the type cannot be changed.
+
+                                       Type |gO| to see the table of contents.
+
+					*v:argv* *argv-variable*
+v:argv		The command line arguments Vim was invoked with.  This is a
+		list of strings.  The first item is the Vim command.
+		See |v:progpath| for the command with full path.
+
+					*v:char* *char-variable*
+v:char		Argument for evaluating 'formatexpr' and used for the typed
+		character when using <expr> in an abbreviation |:map-<expr>|.
+		It is also used by the |InsertCharPre| and |InsertEnter| events.
+
+			*v:charconvert_from* *charconvert_from-variable*
+v:charconvert_from
+		The name of the character encoding of a file to be converted.
+		Only valid while evaluating the 'charconvert' option.
+
+			*v:charconvert_to* *charconvert_to-variable*
+v:charconvert_to
+		The name of the character encoding of a file after conversion.
+		Only valid while evaluating the 'charconvert' option.
+
+					*v:cmdarg* *cmdarg-variable*
+v:cmdarg
+		The extra arguments ("++p", "++enc=", "++ff=") given to a file
+		read/write command.  This is set before an autocommand event
+		for a file read/write command is triggered.  There is a
+		leading space to make it possible to append this variable
+		directly after the read/write command. Note: "+cmd" isn't
+		included here, because it will be executed anyway.
+
+						*v:collate* *collate-variable*
+v:collate	The current locale setting for collation order of the runtime
+		environment.  This allows Vim scripts to be aware of the
+		current locale encoding.  Technical: it's the value of
+		LC_COLLATE.  When not using a locale the value is "C".
+		This variable can not be set directly, use the |:language|
+		command.
+		See |multi-lang|.
+
+					*v:cmdbang* *cmdbang-variable*
+v:cmdbang	Set like v:cmdarg for a file read/write command.  When a "!"
+		was used the value is 1, otherwise it is 0.  Note that this
+		can only be used in autocommands.  For user commands |<bang>|
+		can be used.
+
+				*v:completed_item* *completed_item-variable*
+v:completed_item
+		Dictionary containing the most recent |complete-items| after
+		|CompleteDone|.  Empty if the completion failed, or after
+		leaving and re-entering insert mode.
+		Note: Plugins can modify the value to emulate the builtin
+		|CompleteDone| event behavior.
+
+					*v:count* *count-variable*
+v:count		The count given for the last Normal mode command.  Can be used
+		to get the count before a mapping.  Read-only.  Example: >
+	:map _x :<C-U>echo "the count is " .. v:count<CR>
+<		Note: The <C-U> is required to remove the line range that you
+		get when typing ':' after a count.
+		When there are two counts, as in "3d2w", they are multiplied,
+		just like what happens in the command, "d6w" for the example.
+		Also used for evaluating the 'formatexpr' option.
+
+					*v:count1* *count1-variable*
+v:count1	Just like "v:count", but defaults to one when no count is
+		used.
+
+						*v:ctype* *ctype-variable*
+v:ctype		The current locale setting for characters of the runtime
+		environment.  This allows Vim scripts to be aware of the
+		current locale encoding.  Technical: it's the value of
+		LC_CTYPE.  When not using a locale the value is "C".
+		This variable can not be set directly, use the |:language|
+		command.
+		See |multi-lang|.
+
+					*v:dying* *dying-variable*
+v:dying		Normally zero.  When a deadly signal is caught it's set to
+		one.  When multiple signals are caught the number increases.
+		Can be used in an autocommand to check if Vim didn't
+		terminate normally.
+		Example: >
+	:au VimLeave * if v:dying | echo "\nAAAAaaaarrrggghhhh!!!\n" | endif
+<		Note: if another deadly signal is caught when v:dying is one,
+		VimLeave autocommands will not be executed.
+
+					*v:exiting* *exiting-variable*
+v:exiting	Exit code, or |v:null| before invoking the |VimLeavePre|
+		and |VimLeave| autocmds.  See |:q|, |:x| and |:cquit|.
+		Example: >
+			:au VimLeave * echo "Exit value is " .. v:exiting
+<
+					*v:echospace* *echospace-variable*
+v:echospace	Number of screen cells that can be used for an `:echo` message
+		in the last screen line before causing the |hit-enter-prompt|.
+		Depends on 'showcmd', 'ruler' and 'columns'.  You need to
+		check 'cmdheight' for whether there are full-width lines
+		available above the last line.
+
+					*v:errmsg* *errmsg-variable*
+v:errmsg	Last given error message.
+		Modifiable (can be set).
+		Example: >
+	:let v:errmsg = ""
+	:silent! next
+	:if v:errmsg != ""
+	:  ... handle error
+<
+				*v:errors* *errors-variable* *assert-return*
+v:errors	Errors found by assert functions, such as |assert_true()|.
+		This is a list of strings.
+		The assert functions append an item when an assert fails.
+		The return value indicates this: a one is returned if an item
+		was added to v:errors, otherwise zero is returned.
+		To remove old results make it empty: >
+	:let v:errors = []
+<		If v:errors is set to anything but a list it is made an empty
+		list by the assert function.
+
+					*v:event* *event-variable*
+v:event		Dictionary of event data for the current |autocommand|.  Valid
+		only during the event lifetime; storing or passing v:event is
+		invalid!  Copy it instead: >
+			au TextYankPost * let g:foo = deepcopy(v:event)
+<		Keys vary by event; see the documentation for the specific
+		event, e.g. |DirChanged| or |TextYankPost|.
+			KEY		DESCRIPTION ~

+			regcontents	Text stored in the register as a
+					|readfile()|-style list of lines.
+			regname		Requested register (e.g "x" for "xyy)
+					or the empty string for an unnamed
+					operation.
+			regtype		Type of register as returned by
+					|getregtype()|.
+			visual		Selection is visual (as opposed to,
+					e.g., via motion).

+					|CompleteChanged|.
+			scrollbar	Is |v:true| if popup menu have scrollbar, or
+					|v:false| if not.
+			changed_window	Is |v:true| if the event fired while
+					changing window (or tab) on |DirChanged|.
+			status		Job status or exit code, -1 means "unknown". |TermClose|
+
+					*v:exception* *exception-variable*
+v:exception	The value of the exception most recently caught and not
+		finished.  See also |v:throwpoint| and |throw-variables|.
+		Example: >

+	:endtry
+<		Output: "caught oops".
+
+					*v:false* *false-variable*
+v:false		Special value used to put "false" in JSON and msgpack.  See
+		|json_encode()|.  This value is converted to "v:false" when used
+		as a String (e.g. in |expr5| with string concatenation
+		operator) and to zero when used as a Number (e.g. in |expr5|
+		or |expr7| when used with numeric operators). Read-only.
+
+					*v:fcs_reason* *fcs_reason-variable*
+v:fcs_reason	The reason why the |FileChangedShell| event was triggered.
+		Can be used in an autocommand to decide what to do and/or what
+		to set v:fcs_choice to.  Possible values:
+			deleted		file no longer exists
+			conflict	file contents, mode or timestamp was
+					changed and buffer is modified
+			changed		file contents has changed
+			mode		mode of file changed
+			time		only file timestamp changed
+
+					*v:fcs_choice* *fcs_choice-variable*
+v:fcs_choice	What should happen after a |FileChangedShell| event was
+		triggered.  Can be used in an autocommand to tell Vim what to
+		do with the affected buffer:
+			reload		Reload the buffer (does not work if
+					the file was deleted).
+			edit		Reload the buffer and detect the
+					values for options such as
+					'fileformat', 'fileencoding', 'binary'
+					(does not work if the file was
+					deleted).
+			ask		Ask the user what to do, as if there
+					was no autocommand.  Except that when
+					only the timestamp changed nothing
+					will happen.
+			<empty>		Nothing, the autocommand should do
+					everything that needs to be done.
+		The default is empty.  If another (invalid) value is used then
+		Vim behaves like it is empty, there is no warning message.
+

+		detected.  Empty otherwise.
+
+					*v:fname_in* *fname_in-variable*

+		[1] When doing conversion for a write command (e.g., ":w
+		file") it will be equal to v:fname_in.  When doing conversion
+		for a read command (e.g., ":e file") it will be a temporary
+		file and different from v:fname_in.
+
+					*v:fname_new* *fname_new-variable*
+v:fname_new	The name of the new version of the file.  Only valid while
+		evaluating 'diffexpr'.

+<		Note that the value is restored when returning from a
+		function. |function-search-undo|.
+
+					*v:insertmode* *insertmode-variable*
+v:insertmode	Used for the |InsertEnter| and |InsertChange| autocommand

+		operator) and to zero when used as a Number (e.g. in |expr5|
+		or |expr7| when used with numeric operators). Read-only.
+		In some places `v:null` can be used for a List, Dict, etc.

+		character except for commands starting with <g> or <z>,
+		in which case it is two characters.  Best used alongside
+		|v:prevcount| and |v:register|.  Useful if you want to cancel
+		Operator-pending mode and then use the operator, e.g.: >
