Add: <form name="targetmain"><input type="checkbox" name="targetnew" checked onClick="applywindow(targetlinks)">Open designated links in new window</form>

anywhere on your page to automatically switch the script to manual mode, whereby only checking a checkbox will cause designated links to open in a new window. Customize the form as desired, but preserve key information such as the name attributes and onClick command. Remove form to switch back to auto mode.
