linktarget: "_blank",



//3) Specify operating mode ("auto" or "manual"):

toggleHTML: '<form><input type="checkbox" id="targetcheckbox" checked="checked" /><label for="targetcheckbox">Open off-site links in new window?</label></form>',



//5) If mode is "manual", enable user persistence so the state of the checkbox is remembered?
