+@cindex mark rectangle
When you must specify a rectangle for a command to work on, you do it
by putting the mark at one corner and point at the opposite corner. The
rectangle thus specified is called the @dfn{region-rectangle} because
rectangle is not stored in the kill ring, but in a special place that
can only record the most recent rectangle killed. This is because yanking
a rectangle is so different from yanking linear text that different yank

+@cindex CUA key bindings
+@vindex cua-enable-cua-keys
+ The command @kbd{M-x cua-mode} sets up key bindings that are
+compatible with the Common User Access (CUA) system used in many other
+applications. @kbd{C-x} means cut (kill), @kbd{C-c} copy, @kbd{C-v}
+paste (yank), and @kbd{C-z} undo. Standard Emacs commands like
+@kbd{C-x C-c} still work, because @kbd{C-x} and @kbd{C-c} only take
+effect when the mark is active (and the region is highlighted).
+However, if you don't want to override these bindings Emacs at all, set
+@code{cua-enable-cua-keys} to @code{nil}.
+
+ In CUA mode, using @kbd{Shift} together with the movement keys
+activates and highlights the region over which they move. The
+standard (unshifted) movement keys deactivate the mark, and typed text
+replaces the active region as in Delete-Selection mode
+(@pxref{Graphical Kill}).
+
+ To enter an Emacs command like @kbd{C-x C-f} while the mark is
+active, use one of the following methods: either hold @kbd{Shift}
+together with the prefix key, e.g. @kbd{S-C-x C-f}, or quickly type
+the prefix key twice, e.g. @kbd{C-x C-x C-f}.
+
+@cindex rectangle highlighting
+ CUA mode provides enhanced rectangle support with visible
+rectangle highlighting. Use @kbd{C-RET} to start a rectangle,
+extend it using the movement commands, and cut or copy it using
+@kbd{C-x} or @kbd{C-c}. @kbd{RET} moves the cursor to the next
+(clockwise) corner of the rectangle, so you can easily expand it in
+any direction. Normal text you type is inserted to the left or right
+of each line in the rectangle (on the same side as the cursor).
+
+ With CUA you can easily copy text and rectangles into and out of
+registers by providing a one-digit numeric prefix the the kill, copy,
+and yank commands, e.g. @kbd{C-1 C-c} copies the region into register
+@code{1}, and @kbd{C-2 C-v} yanks the contents of register @code{2}.
+
+@cindex global mark
+ CUA mode also has a global mark feature which allows easy moving and
+copying of text between buffers. Use @kbd{C-S-SPC} to toggle the
+global mark on and off. When the global mark is on, all text that you
+kill or copy is automatically inserted at the global mark, and text
+you type is inserted at the global mark rather than at the current
+position.
+
+ For example, to copy words from various buffers into a word list in
+a given buffer, set the global mark in the target buffer, then
+navigate to each of the words you want in the list, mark it (e.g. with
+@kbd{S-M-f}), copy it to the list with @kbd{C-c} or @kbd{M-w}, and
+insert a newline after the word in the target list by pressing
+@key{RET}.
