@node Buffers, Windows, Files, Top
A buffer's size cannot be larger than some maximum, which is defined
by the largest buffer position representable by the @dfn{Emacs integer}
data type. This is because Emacs tracks buffer positions using that
-data type. For 32-bit machines, the largest buffer size is 128
+data type. For 32-bit machines, the largest buffer size is 256
megabytes.
@menu
specify a name that is in use for some other buffer, an error happens and
no renaming is done.
+@findex rename-uniquely
@kbd{M-x rename-uniquely} renames the current buffer to a similar
name with a numeric suffix added to make it both different and unique.
This command does not need an argument. It is useful for creating
@item 1

+Immediately set up two windows, with this line's buffer selected in

@item b
Bury the buffer listed on this line.

and select the buffer list manually, you can use all of the commands
described here.
- The buffer @samp{*Buffer List*} is not updated automatically when
+ Normally, the buffer @samp{*Buffer List*} is not updated automatically when
buffers are created and killed; its contents are just text. If you have
created, deleted or renamed buffers, the way to update @samp{*Buffer
List*} to show what you have done is to type @kbd{g}
(@code{revert-buffer}) or repeat the @code{buffer-menu} command.
+ The @samp{*Buffer List*} buffer does automatically update every
+@code{auto-revert-interval} seconds if you enable Auto Revert mode in
+it. (As long as it is not marked modified.) Global Auto Revert mode
+does not update the @samp{*Buffer List*} buffer by default, but it
+does if @code{global-auto-revert-non-file-buffers} is non-@code{nil}.
+@inforef{Autorevert,, emacs-xtra}, for details.

The command @code{buffer-menu-other-window} works the same as
@code{buffer-menu}, except that it displays the buffers list in
another window.
