-@subsection Standard scrolling commands
-Here is the list of commands which are configured by default to be
-``scrolling'' commands in an incremental search, together with their
-usual bindings:
-@subsubsection Commands which scroll the window:
-@table @asis
-@item @code{scroll-bar-toolkit-scroll} (@kbd{@key{vertical-scroll-bar}@key{mouse-1}} in X-Windows)
-@itemx @code{mac-handle-scroll-bar-event} (@kbd{@key{vertical-scroll-bar}@key{mouse-1}} on a Mac)
-@itemx @code{w32-handle-scroll-bar-event} (@kbd{@key{vertical-scroll-bar}@key{mouse-1}} in MS-Windows)
-@item @code{recenter} (@kbd{C-l}) @xref{Scrolling}.
-@itemx @code{reposition-window} (@kbd{C-M-l}) @xref{Scrolling}.
-@itemx @code{scroll-up} (@kbd{@key{NEXT}}) @xref{Scrolling}.
-@itemx @code{scroll-down} (@kbd{@key{PRIOR}}) @xref{Scrolling}.
-@end table
-
-@subsubsection Commands which act on the other window:
-@table @asis
-@item @code{list-buffers} (@kbd{C-x C-b}) @xref{List Buffers}.
-@itemx @code{scroll-other-window} (@kbd{C-M-v}) @xref{Other Window}.
-@itemx @code{scroll-other-window-down} (@kbd{C-M-S-v}) @xref{Other Window}.
-@itemx @code{beginning-of-buffer-other-window} (@kbd{M-@key{home}})
-@itemx @code{end-of-buffer-other-window} (@kbd{M-@key{end}})
-@end table
-
-@subsubsection Commands which change the window layout:
-@table @asis
-@item @code{delete-other-windows} (@kbd{C-x 1}) @xref{Change Window}.
-@itemx @code{balance-windows} (@kbd{C-x +}) @xref{Change Window}.
-@itemx @code{split-window-vertically} (@kbd{C-x 2}) @xref{Split Window}.
-@itemx @code{enlarge-window} (@kbd{C-x ^}) @xref{Change Window}.
-@end table
-
-@subsection Configuring other commands as scrolling commands
-To do this, set a command's isearch-scroll property to the value t.
-For example:
-
-@example
-@code{(put 'my-command 'isearch-scroll t)}
-@end example
-
-You should only thus configure commands which are ``safe'': i.e., they
-won't leave emacs in an inconsistent state when executed within a
-search - that is to say, the following things may be changed by a
-command only temporarily, and must be restored before the command
-finishes:
-
-@enumerate
-@item
-Point.
-@item
-The buffer contents.
-@item
-The selected window and selected frame.
-@item
-The current match-data @xref{Match Data,,,elisp}.
-@end enumerate
-
-Additionally, the command must not delete the current window and must
-not itself attempt an incremental search. It may, however, change the
-window's size, or create or delete other windows and frames.
-
-Note that an attempt by a command to scroll the text
-@emph{horizontally} won't work, although it will do no harm - any such
-scrolling will be overriden and nullified by the display code.

-@node Replace, Other Repeating Search, Configuring Scrolling, Search
+there is a default value in @code{default-case-fold-search} that you
+can also set. @xref{Locals}. This variable applies to nonincremental
+searches also, including those performed by the replace commands
+(@pxref{Replace}) and the minibuffer history matching commands
+(@pxref{Minibuffer History}).
+
+ Several related variables control case-sensitivity of searching and
+matching for specific commands or activities. For instance,
+@code{tags-case-fold-search} controls case sensitivity for
+@code{find-tag}. To find these variables, do @kbd{M-x
+apropos-variable @key{RET} case-fold-search @key{RET}}.
