Keyboard Short cuts - external script library

Hello everyone - I am a bit new to all this. Apologies if this is not the correct forum…
I am trying to use the JavaScript Library shortcut.js
I have used Scott Butler’s slide from Servoy World as a starting point (see attachment)

function StartShortcuts()
{
globals.customJS = “” +
“<script type=text/javascript src="/js/shortcut.js">” +
“” +
“” +
//the call to the servoy method executed from above
“<a href="javascript:globals.JStest()" id="jsBridge">Hidden” +
“”
}

Can anyone spare a few moments to give me some clues as to how to get this to work ?
Thanks
