I have a component with some fields and what not on there, basically I am trying to get a button to click using Shift + c, I have setup the short key via the app. this is what i have in my Component and Script. the ID of my component is called theComponent and the page where I use the component, id is called thePage. when i hit Shift + C nothing happens. 

<script>
sforce.console.addEventListener('SHIFT+C', function() {
                document.getElementById(
                        '{!$Component.thePage.externalComponentId.theComponent.theForm.pageBlockSection.blockButtons.addContact}').click();
            });
    </script>
    <apex:form id="theForm">
    
        <apex:pageBlock mode="detail" id="pageBlockSection" rendered="{!!currentContact}" >
            <apex:pageBlockButtons id="blockButtons">
                <apex:actionStatus id="finishChangedNew" onstart="openPopUp()"/>
