For instance, if you type @kbd{C-s} and then @kbd{F}, that puts the
cursor after the first @samp{F} that occurs in the buffer after the
-starting point. Then if you then type @kbd{O}, the cursor moves to
-just after the first @samp{FO}; the @samp{F} in that @samp{FO} might
-not be the first @samp{F} previously found. After another @kbd{O},
-the cursor moves to just after the first @samp{FOO}.

@cindex faces for highlighting search matches

By default, incremental search performs @dfn{lax space matching}:
each space, or sequence of spaces, matches any sequence of one or more
spaces in the text. Hence, @samp{foo bar} matches @samp{foo bar},
-@samp{foo bar}, @samp{foo bar}, and so on (but not @samp{foobar}).
-More precisely, Emacs matches each sequence of space characters in the
-search string to a regular expression specified by the variable
-@code{search-whitespace-regexp}. For example, to make spaces match
-sequences of newlines as well as spaces, set it to
+@samp{foo@w{ }bar}, @samp{foo@w{ }bar}, and so on (but not
+@samp{foobar}). More precisely, Emacs matches each sequence of space
+characters in the search string to a regular expression specified by
+the variable @code{search-whitespace-regexp}. For example, to make
+spaces match sequences of newlines as well as spaces, set it to
@samp{"[[:space:]\n]+"}.
To toggle lax space matching, type @kbd{M-s @key{SPC}}
