 @subsection Scrolling During Incremental Search
 
 @vindex isearch-allow-scroll
-  You can enable the use of vertical scrolling during incremental
-search (without exiting the search) by setting the customizable
-variable @code{isearch-allow-scroll} to a non-@code{nil} value.  This
-applies to using the vertical scroll-bar and to certain keyboard
-commands such as @code{scroll-down-command}, @code{scroll-up-command}
-and @code{recenter} (@pxref{Scrolling}).  You must run these commands
-via their key sequences to stay in the search---typing @kbd{M-x} will
-terminate the search.  You can give prefix arguments to these commands
-in the usual way.
-
-  This feature won't let you scroll the current match out of visibility,
-however.
-
-  The feature also affects some other commands, such as @kbd{C-x 2}
-(@code{split-window-vertically}) and @kbd{C-x ^}
-(@code{enlarge-window}) which don't exactly scroll but do affect where
-the text appears on the screen.  In general, it applies to any command
-whose name has a non-@code{nil} @code{isearch-scroll} property.  So you
-can control which commands are affected by changing these properties.
+  Normally, scrolling commands exit incremental search.  If you change
+the variable @code{isearch-allow-scroll} to a non-@code{nil} value,
+that enables the use of the scroll-bar, as well as keyboard scrolling
+commands like @kbd{C-v}, @kbd{M-v}, and @kbd{C-l} (@pxref{Scrolling}).
+This applies only to calling these commands via their bound key
+sequences---typing @kbd{M-x} will still exit the search.  You can give
