Transient Mark mode is enabled). All the primitives that change the
buffer set @code{deactivate-mark}, to deactivate the mark when the
command is finished.
+
+To write Lisp code that modifies the buffer without causing
+deactivation of the mark at the end of the command, bind
+@code{deactivate-mark} to @code{nil} around the code that does the
+modification. For example:
+
+@example
+(let (deactivate-mark)
+ (insert " "))
+@end example
@end defvar
@defun deactivate-mark
