-  Some Emacs buffers include references you can follow, or commands
-you can activate.  These include names of files, of buffers, of
-possible completions, of matches for a pattern, as well as the buttons
-in Help buffers and customization buffers.  You can follow the
-reference or activate the command by moving point to it and typing
address@hidden  You can also do this with the mouse, using either
address@hidden or @kbd{Mouse-2}.
-
-  Since yanking text into a read-only buffer is not allowed, these
-buffers generally define @kbd{Mouse-2} to follow a reference or
-activate a command.  For example, if you click @kbd{Mouse-2} on a file
-name in a Dired buffer, you visit that file.  If you click
address@hidden on an error message in the @samp{*Compilation*} buffer,
-you go to the source code for that error message.  If you click
address@hidden on a completion in the @samp{*Completions*} buffer, you
-choose that completion.
-
-  However, most applications use @kbd{Mouse-1} to do this sort of
-thing, so Emacs implements this too.  If you click @kbd{Mouse-1}
-quickly on a reference or button, it follows or activates.  If you
-click slowly, it moves point as usual.  Dragging, meaning moving the
-mouse while it is held down, also has its usual behavior of setting
-the region.
address@hidden mouse-highlight
+  Some Emacs buffers include @dfn{buttons} which perform some action,
+such as following a reference.  A button is a stretch of text that
+usually stands out in some way; it may be underlined, or a box may be
+drawn around it.  If you move the mouse over a button, the shape of
+the mouse cursor changes and the button lights up (if you change the
+variable @code{mouse-highlight} to @code{nil}, Emacs disables this
+highlighting).
+
+  You can activate a button by moving point to it and typing
address@hidden, or by clicking either @kbd{Mouse-1} or @kbd{Mouse-2} on the
+button.  For example, typing @key{RET} or clicking on a file name in a
+Dired buffer visits that file (@pxref{Dired}).  Doing it on an error
+message in the @samp{*Compilation*} buffer goes to the source code for
+that error message (@pxref{Compilation}).  Doing it on a completion in
+the @samp{*Completions*} buffer chooses that completion
+(@pxref{Completion}).
+
+  Although clicking @key{Mouse-1} on a button usually activates that
+button, if you hold the mouse button down for a short period of time
+before releasing it (specifically, for more than 450 milliseconds),
+then Emacs moves point where you clicked instead.  This behavior
+allows you to use the mouse to move point over a button without
+following it.  Dragging, meaning moving the mouse while it is held
+down, has its usual behavior of setting the region.
 
 @vindex mouse-1-click-in-non-selected-windows
-  Normally, the @kbd{Mouse-1} click behavior is performed on links in
-any window.  The variable @code{mouse-1-click-in-non-selected-windows}
-controls whether @kbd{Mouse-1} has this behavior even in non-selected
-windows, or only in the selected window.
-
address@hidden mouse-highlight
-  You can usually tell when @kbd{Mouse-1} and @kbd{Mouse-2} have this
-special sort of meaning because the sensitive text highlights when you
-move the mouse over it.  The variable @code{mouse-highlight} controls
-whether to do this highlighting always (even when such text appears
-where the mouse already is), never, or only immediately after you move
-the mouse.
+  Normally, clicking @key{Mouse-1} on a button activates the button
+even if it is in an un-selected window.  If you change the variable
address@hidden to @code{nil}, clicking
address@hidden on a button in an un-selected window moves point to the
+clicked position and selects that window, without activating the
+button.
 
 @vindex mouse-1-click-follows-link
-  In Emacs versions before 22, only @kbd{Mouse-2} follows links and
address@hidden always sets point.  If you prefer this older behavior,

-represents the entire length of the buffer.
-
-  You can use @kbd{Mouse-2} (normally, the middle button) in the scroll
-bar to move or drag the inner box up and down.  If you move it to the
-top of the scroll bar, you see the top of the buffer.  If you move it to
-the bottom of the scroll bar, you see the bottom of the buffer.
-

+
+  When Emacs is compiled with GTK support on the X window system, or
+in operating systems such as Microsoft Windows or Mac OS, you can use
+the scroll bar as you do in other graphical applications.  If you
+click @key{Mouse-1} on the scroll bar's up and down buttons, that
+scrolls the window by one line at a time.  Clicking @key{Mouse-1}
+above or below the scroll bar's inner box scrolls the window by nearly
+the entire height of the window, like @kbd{M-v} and @kbd{C-v}
+respectively (@pxref{Moving Point}).  Dragging the inner box with
address@hidden scrolls the window continuously.
+
+  If Emacs is compiled without GTK support on the X window system, the
+scroll bar behaves differently.  The scroll bar's inner box is drawn
+to represent the portion of the buffer currently displayed, with the
+entire height of the scroll bar representing the entire length of the
+buffer.  @key{Mouse-1} anywhere on the scroll bar scrolls forward like
address@hidden, and @key{Mouse-3} scrolls backward like @kbd{M-v}.
+Clicking @key{Mouse-2} in the scroll bar lets you move or drag the
