Как сделать отправку сообщения (Ctrl+Enter) - кнопкой?

jQuery(function(a){var c=!1;a(document).keydown(function(b){if(13==b.which&&b.ctrlKey){b.preventDefault();if(window.getSelection)var c=window.getSelection();else document.getSelection?c=document.getSelection():document.selection&&(c=document.selection.createRange().text);if(""==c)return!1;if(255<c.toString().length)return DLEalert(dle_big_text,dle_info),!1;b={};b[dle_act_lang[3]]=function(){a(this).dialog("close")};b[dle_p_send]=function(){if(1>a("#dle-promt-text").val().length)a("#dle-promt-text").addClass("ui-state-error");
else{var b=a("#dle-promt-text").val(),c=a("#orfom").text();a(this).dialog("close");a("#dlepopup").remove();a.post(dle_root+"engine/ajax/complaint.php",{seltext:c,text:b,user_hash:dle_login_hash,action:"orfo",url:window.location.href},function(a){"ok"==a?DLEalert(dle_p_send_ok,dle_info):DLEalert(a,dle_info)})}};a("#dlepopup").remove();a("body").append("<div id='dlepopup' class='dle-promt' title='"+dle_orfo_title+"' style='display:none'><textarea name='dle-promt-text' id='dle-promt-text' class='ui-widget-content ui-corner-all' style='width:97%;height:80px;'></textarea><div id='orfom' style='display:none'>"+
c+"</div></div>");a("#dlepopup").dialog({autoOpen:!0,width:600,resizable:!1,dialogClass:"modalfixed dle-popup-complaint",buttons:b});a(".modalfixed.ui-dialog").css({position:"fixed"});a("#dlepopup").dialog("option","position",["0","0"])}});a("img[data-maxwidth]").each(function(){var b=a(this).width(),d=a(this).data("maxwidth");b>d&&(a(this).width(d),a(this).wrap('<a href="'+a(this).attr("src")+'" onclick="return hs.expand(this)"></a>'),"undefined"==typeof hs&&0==c&&(c=!0,a.getScript(dle_root+"engine/classes/highslide/highslide.js",
function(){hs.graphicsDir=dle_root+"engine/classes/highslide/graphics/";hs.numberOfImagesToPreload=0;hs.captionEval="this.thumb.alt";hs.showCredits=!1;hs.align="center";hs.transitions=["expand","crossfade"]})))})});

$('#myButton').click(function(){
   var e = jQuery.Event( "keydown", { which: 13, ctrlKey: true } );
   $(document).trigger(e);
});
