After BufWritePost.
				Before BufDelete.
				Triggers for all loaded buffers when Vim is
				going to exit.
				NOTE: Current buffer "%" is not the target
				buffer "<afile>", "<abuf>". |<buffer=abuf>|
				Do not switch buffers or windows!
				Not triggered when exiting and v:dying is 2 or
				more.
							*BufWinEnter*
BufWinEnter			After a buffer is displayed in a window.  This
				may be when the buffer is loaded (after
				processing modelines) or when a hidden buffer
				is displayed (and is no longer hidden).

				Not triggered for |:split| without arguments,
				since the buffer does not change, or :split
				with a file already open in a window.
				Triggered for ":split" with the name of the
				current buffer, since it reloads that buffer.
							*BufWinLeave*
BufWinLeave			Before a buffer is removed from a window.
				Not when it's still visible in another window.
				Also triggered when exiting.
				Before BufUnload, BufHidden.
				NOTE: Current buffer "%" is not the target
				buffer "<afile>", "<abuf>". |<buffer=abuf>|
				Not triggered when exiting and v:dying is 2 or
				more.
							*BufWipeout*
BufWipeout			Before completely deleting a buffer.  The
				BufUnload and BufDelete events may be called
				first (if the buffer was loaded and was in the
				buffer list).  Also used just before a buffer
				is renamed (also when it's not in the buffer
				list).
				NOTE: Current buffer "%" is not the target
				buffer "<afile>", "<abuf>". |<buffer=abuf>|
				Do not change to another buffer.
						*BufWrite* *BufWritePre*
BufWrite or BufWritePre		Before writing the whole buffer to a file.
							*BufWriteCmd*
BufWriteCmd			Before writing the whole buffer to a file.
				Should do the writing of the file and reset
				'modified' if successful, unless '+' is in
				'cpo' and writing to another file |cpo-+|.
				The buffer contents should not be changed.
				When the command resets 'modified' the undo
				information is adjusted to mark older undo
				states as 'modified', like |:write| does.  Use
				the |'[| and |']| marks for the range of lines.
				|Cmd-event|
							*BufWritePost*
BufWritePost			After writing the whole buffer to a file
				(should undo the commands for BufWritePre).
							*ChanInfo*
ChanInfo			State of channel changed, for instance the
				client of a RPC channel described itself.
				This is triggered even when inside an
				autocommand defined without |autocmd-nested|.
				Sets these |v:event| keys:
				    info	as from |nvim_get_chan_info()|
							*ChanOpen*
ChanOpen			Just after a channel was opened.
				This is triggered even when inside an
				autocommand defined without |autocmd-nested|.
				Sets these |v:event| keys:
				    info	as from |nvim_get_chan_info()|
							*CmdUndefined*
CmdUndefined			When a user command is used but it isn't
				defined.  Useful for defining a command only
				when it's used.  The pattern is matched
				against the command name.  Both <amatch> and
				<afile> expand to the command name.
				This is triggered even when inside an
				autocommand defined without |autocmd-nested|.
				NOTE: Autocompletion won't work until the
				command is defined.  An alternative is to
				always define the user command and have it
				invoke an autoloaded function.  See |autoload|.
							*CmdlineChanged*
CmdlineChanged			After a change was made to the text inside
				command line.  Be careful not to mess up the
				command line, it may cause Vim to lock up.
				<afile> expands to the |cmdline-char|.
							*CmdlineEnter*
CmdlineEnter			After entering the command-line (including
				non-interactive use of ":" in a mapping: use
				|<Cmd>| instead to avoid this).
				The pattern is matched against |cmdline-char|.
				<afile> expands to the |cmdline-char|.
				Sets these |v:event| keys:
				    cmdlevel
				    cmdtype
							*CmdlineLeave*
CmdlineLeave			Before leaving the command-line (including
				non-interactive use of ":" in a mapping: use
				|<Cmd>| instead to avoid this).
