@findex transient-mark-mode
To turn off Transient Mark mode, type @kbd{M-x transient-mark-mode}.
-This command toggles the mode; you can use the same command to turn
-Transient Mark mode on again. You can also turn off Transient Mark
-mode using the menu bar: in the @samp{Options} menu, toggle the
-@samp{Active Region Highlighting} menu item.

Here are the details of how Emacs behaves when Transient Mark mode
is off:
@kbd{C-s}, first set the mark where point was.
@item
-Some commands, which ordinarily operate on the region when the mark is
-active, instead act on the entire buffer. For instance, @kbd{C-x u}
-normally reverses changes within the region if the mark is active;
-when Transient Mark mode is off, it acts on the entire buffer.
-However, you can type @kbd{C-u C-x u} to make it operate on the
-region. @xref{Undo}. Other commands that act this way are identified
-in their own documentation.
+Some commands, which ordinarily act on the region when the mark is
+active, no longer do so. For example, normally @kbd{M-%}
+(@code{query-replace}) performs replacements within the region, if the
+mark is active. When Transient Mark mode is off, it always operates
+from point to the end of the buffer. Commands that act this way are
+identified in their own documentation.
@end itemize
While Transient Mark mode is off, you can activate it temporarily
@item C-u C-x C-x
@kindex C-u C-x C-x
-Activate the mark without changing it; enable Transient Mark mode just
-once, until the mark is deactivated. (This is the @kbd{C-x C-x}
-command, @code{exchange-point-and-mark}, with a prefix argument.)
+Activate the mark and enable Transient Mark mode temporarily, until
+the mark is next deactivated. (This is the @kbd{C-x C-x} command,
+@code{exchange-point-and-mark}, with a prefix argument.)

These commands set or activate the mark, and enable Transient Mark
