+The Mark Ring
+-------------
+
+ Aside from delimiting the region, the mark is also useful for marking
+a spot that you may want to go back to. To make this feature more
+useful, Emacs remembers 16 previous locations of the mark in the "mark
+ring". Most commands that set the mark push the old mark onto this
+ring. To return to a marked location, use `C-u C-<SPC>' (or `C-u
+C-@'); this is the command `set-mark-command' given a numeric argument.
+The command moves point to where the mark was, and restores the mark
+from the ring of former marks. Repeated use of this command moves point
+to all the old marks on the ring, one by one. The marks you have seen
+go to the end of the ring, so no marks are lost.
+
+ Each buffer has its own mark ring. All editing commands use the
+current buffer's mark ring. In particular, `C-u C-<SPC>' always stays
+in the same buffer.
+
+ Many commands that can move long distances, such as `M-<'
+(`beginning-of-buffer'), start by setting the mark and saving the old
+mark on the mark ring. This makes it easier for you to move back
+later. Searches set the mark, unless they do not actually move point.
+When a command sets the mark, `Mark Set' is printed in the echo area.
+
+ The variable `mark-ring-max' is the maximum number of entries to
+keep in the mark ring. If that many entries exist and another entry is
+added, the last entry in the list is discarded. Repeating `C-u
+C-<SPC>' circulates through the entries that are currently in the ring.
+
+ The variable `mark-ring' holds the mark ring itself, as a list of
+marker objects in the order most recent first. This variable is local
+in every buffer.

+Selecting Text with the Mouse
+=============================
+
+ If you are using XEmacs under X, you can use the mouse pointer to
+select text. (The normal mouse pointer is an I-beam, the same pointer
+that `xterm' uses.)
+
+ The glyph variable `text-pointer-glyph' controls the shape of the
+mouse pointer when over text. You can also control the shape of the
+mouse pointer when over nontext using `nontext-pointer-glyph', and the
+shape of the mouse pointer when over the modeline using
+`modeline-pointer-glyph'. (Remember, you should use `set-glyph-image',
+not `setq', to set one of these variables.)
+
+ If you want to get fancy, you can set the foreground and background
+colors of the mouse pointer by setting the `pointer' face.
+
+ There are two ways to select a region of text with the mouse:
+
+ To select a word in text, double-click with the left mouse button
+while the mouse cursor is over the word. The word is highlighted when
+selected. On monochrome monitors, a stippled background indicates that a
+region of text has been highlighted. On color monitors, a color
+background indicates highlighted text. You can triple-click to select
+whole lines.
+
+ To select an arbitrary region of text:
+
+ 1. Move the mouse cursor over the character at the beginning of the
+ region of text you want to select.
+
+ 2. Press and hold the left mouse button.
+
+ 3. While holding the left mouse button down, drag the cursor to the
+ character at the end of the region of text you want to select.
+
+ 4. Release the left mouse button.
+ The selected region of text is highlighted.
+
+ Once a region of text is selected, it becomes the primary X selection
+(*note Using X Selections::) as well as the Emacs selected region. You
+can paste it into other X applications and use the options from the
+Edit pull-down menu on it. Since it is also the Emacs region, you can
+use Emacs region commands on it.

-Scrolling
-=========
-
- If a buffer contains text that is too large to fit entirely within
-the window that is displaying the buffer, XEmacs shows a contiguous
-section of the text. The section shown always contains point.
-
- "Scrolling" means moving text up or down in the window so that
-different parts of the text are visible. Scrolling forward means that
-text moves up, and new text appears at the bottom. Scrolling backward
-moves text down and new text appears at the top.
-
- Scrolling happens automatically if you move point past the bottom or
-top of the window. You can also explicitly request scrolling with the
-commands in this section.
-
-`C-l'
- Clear frame and redisplay, scrolling the selected window to center
- point vertically within it (`recenter').
-
-`C-v'
-`pgdn'
-`next'
- Scroll forward (a windowful or a specified number of lines)
- (`scroll-up').
-
-`M-v'
-`pgup'
-`prior'
- Scroll backward (`scroll-down').
-
-`ARG C-l'
- Scroll so point is on line ARG (`recenter').
-
- The most basic scrolling command is `C-l' (`recenter') with no
-argument. It clears the entire frame and redisplays all windows. In
-addition, it scrolls the selected window so that point is halfway down
-from the top of the window.
-
- The scrolling commands `C-v' and `M-v' let you move all the text in
-the window up or down a few lines. `C-v' (`scroll-up') with an
-argument shows you that many more lines at the bottom of the window,
-moving the text and point up together as `C-l' might. `C-v' with a
-negative argument shows you more lines at the top of the window.
-`Meta-v' (`scroll-down') is like `C-v', but moves in the opposite
-direction.
-
- To read the buffer a windowful at a time, use `C-v' with no
-argument. `C-v' takes the last two lines at the bottom of the window
-and puts them at the top, followed by nearly a whole windowful of lines
-not previously visible. Point moves to the new top of the window if it
-was in the text scrolled off the top. `M-v' with no argument moves
-backward with similar overlap. The number of lines of overlap across a
-`C-v' or `M-v' is controlled by the variable
-`next-screen-context-lines'; by default, it is two.
-
- Another way to scroll is using `C-l' with a numeric argument. `C-l'
-does not clear the frame when given an argument; it only scrolls the
-selected window. With a positive argument N, `C-l' repositions text to
-put point N lines down from the top. An argument of zero puts point on
-the very top line. Point does not move with respect to the text;
-rather, the text and point move rigidly on the frame. `C-l' with a
-negative argument puts point that many lines from the bottom of the
-window. For example, `C-u - 1 C-l' puts point on the bottom line, and
-`C-u - 5 C-l' puts it five lines from the bottom. Just `C-u' as
-argument, as in `C-u C-l', scrolls point to the center of the frame.
-
- Scrolling happens automatically if point has moved out of the visible
-portion of the text when it is time to display. Usually scrolling is
-done to put point vertically centered within the window. However, if
-the variable `scroll-step' has a non-zero value, an attempt is made to
-scroll the buffer by that many lines; if that is enough to bring point
-back into visibility, that is what happens.

-
- If you set `scroll-step' to a small value because you want to use
-arrow keys to scroll the screen without recentering, the redisplay
-preemption will likely make XEmacs keep recentering the screen when
-scrolling fast, regardless of `scroll-step'. To prevent this, set
-`scroll-conservatively' to a small value, which will have the result of
-overriding the redisplay preemption.
