After exiting a search, you can search for the same string again by
typing just @kbd{C-s C-s}. The first @kbd{C-s} is the key that
-invokes incremental search, and the second @kbd{C-s} means ``search
-again''. Similarly, @kbd{C-r C-r} searches backward for the last

+again. Similarly, @kbd{C-r C-r} searches backward for the last
search string. In determining the last search string, it doesn't
matter whether the string was searched for with @kbd{C-s} or
@kbd{C-r}.
If an incremental search fails in the minibuffer, it tries searching
the minibuffer history. @xref{Minibuffer History}. You can visualize
-the minibuffer and its history as a series of ``pages'', with the
+the minibuffer and its history as a series of pages, with the
earliest history element on the first page and the current minibuffer
on the last page. A forward search, @kbd{C-s}, searches forward to
later pages; a reverse search, @kbd{C-r}, searches backwards to
parenthetical grouping; it is a separate feature that is assigned as a
second meaning to the same @samp{\( @dots{} \)} construct. In practice
there is usually no conflict between the two meanings; when there is
-a conflict, you can use a ``shy'' group.

you can't refer back to it with @samp{\@var{d}} (see below). This is
useful in mechanically combining regular expressions, so that you can
add groups for syntactic purposes without interfering with the
