Hi,<div>I am annoyed by the behavior that out of a sudden emacs set marker on current cursor point and if I go to the end of line or go to the end of buffer, it selects the regions and by the time I type, that region is cut &amp; gone! </div>
<div><br></div><div>I want to change its behavior so unless I press Ctrl+@, emacs never sets marker itself, how do I do that?</div><div><br></div><div>Best,</div><div>Yuan</div>
