@var{bufname} @key{RET}}. This runs the command
@code{switch-to-buffer} with argument @var{bufname}. While entering
the buffer name, you can use the usual minibuffer completion and
-history commands (@pxref{Minibuffer}). An empty argument to @kbd{C-x
-b} specifies the buffer that was current most recently among those not
-now displayed in any window.

realizing that @key{TAB} did not complete far enough to yield the
desired buffer name (@pxref{Completion}). Emacs asks for confirmation
by putting the message @samp{[Confirm]} in the minibuffer; type
-@key{RET} again to confirm and visit the buffer.

-@vindex confirm-nonexistent-file-or-buffer
- The variable @code{confirm-nonexistent-file-or-buffer} controls
-whether Emacs asks for confirmation before visiting a buffer that did
-not previously exist. The default value, @code{after-completion},
-gives the behavior we have just described. If the value is
-@code{nil}, Emacs never asks for confirmation; for any other
-non-@code{nil} value, Emacs always asks for confirmation. This
-variable also affects the @code{find-file} command (@pxref{Visiting}).

One reason to create a new buffer is to use it for making temporary
notes. If you try to save it, Emacs asks for the file name to use.
@kindex C-x 4 b
@findex switch-to-buffer-other-window
-@vindex even-window-heights
To select a buffer in a window other than the current one, type
@kbd{C-x 4 b} (@code{switch-to-buffer-other-window}). This prompts
for a buffer name using the minibuffer, displays that buffer in
-another window, and selects that window. By default, if displaying
-the buffer causes two vertically adjacent windows to be displayed, the
-heights of those windows are evened out; to countermand that and
-preserve the window configuration, set the variable
-@code{even-window-heights} to @code{nil}.

@kindex C-x 5 b
@findex switch-to-buffer-other-frame
Similarly, @kbd{C-x 5 b} (@code{switch-to-buffer-other-frame})
prompts for a buffer name, displays that buffer in another frame, and
-selects that frame.

In addition, @kbd{C-x C-f}, and any other command for visiting a
file, can also be used to switch to an existing file-visiting buffer.

-@vindex display-buffer-reuse-frames
- You can control how certain buffers are handled by these commands by
-customizing the variables @code{special-display-buffer-names},
-@code{special-display-regexps}, @code{same-window-buffer-names}, and
-@code{same-window-regexps}. See @ref{Force Same Window}, and
-@ref{Special Buffer Frames}, for more about these variables. In
-addition, if the value of @code{display-buffer-reuse-frames} is
-non-@code{nil}, and the buffer you want to switch to is already
-displayed in some frame, Emacs will just raise that frame.
