Rename the current buffer by adding @samp{<@var{number}>} to the end.

Scroll through buffer @var{buffer}. @xref{View Mode}.

@findex rename-buffer
- @kbd{M-x rename-buffer} changes the name of the current buffer. You
-specify the new name as a minibuffer argument; there is no default.
-If you 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

@findex toggle-truncate-lines
Horizontal scrolling automatically causes line truncation
(@pxref{Horizontal Scrolling}). You can explicitly enable line
-truncation for a particular buffer with the command @kbd{M-x
-toggle-truncate-lines}. This works by locally changing the variable
-@code{truncate-lines}. If that variable is non-@code{nil}, long lines
-are truncated; if it is @code{nil}, they are continued onto multiple
-screen lines. Setting the variable @code{truncate-lines} in any way
-makes it local to the current buffer; until that time, the default
-value, which is normally @code{nil}, is in effect.

If a split window becomes too narrow, Emacs may automatically enable
line truncation. @xref{Split Window}, for the variable
buffer is deleted, so the buffer is left containing just the text newly
copied into it.
- The command @kbd{M-x insert-buffer} can be used to retrieve the
-accumulated text from another buffer. This prompts for the name of a
-buffer, and inserts a copy of all the text in that buffer into the
-current buffer at point, leaving point at the beginning of the
-inserted text. It also adds the position of the end of the inserted
-text to the mark ring, without activating the mark. @xref{Buffers},

Instead of accumulating text in a buffer, you can append text
directly into a file with @kbd{M-x append-to-file}. This prompts for
search buffer due to too many matches being highlighted.

-** 'revert-buffer' is now bound to 'C-x x g' globally.
+** A new keymap for buffer actions has been added.
+The 'C-x x' keymap now holds keystrokes for various buffer-oriented
+commands. The new keystrokes are 'C-x x g' ('revert-buffer'),
+'C-x x r' ('rename-buffer'), 'C-x x u' ('rename-uniquely'),
+'C-x x i' ('insert-buffer') and 'C-x x t' ('toggle-truncate-lines').
