In BigBlueButton.mxml, find the loadKeyCombos() method. This collects all available global shortcuts into an object called keyCombos. The Opinion module has only one global shortcut, so the only line we need to add to this method is:

<code>keyCombos[modifier+(ResourceUtil.getInstance().getString('bbb.shortcutkey.focus.opinion') as String)] = ShortcutEvent.FOCUS_OPINION_MODULE;</code>

'''NOTE: Generally, your module's only global shortcut will be to move the applications focus into your module, although this is not a rule by any means.'''
