GhostText

[ArunPatal]

Hello,
GhostText is very nice feature but please make a example of how to use it properly.
Am using it like:

var ghostTextArray = ["foo", "bar"];
//Find Match Text
editor.on('input', function(){
  var position = editor.getCursorPosition();
  var token = editor.session.getTokenAt(position.row, position.column);

  for(var i = 0; i < ghostTextArray.length; i++){
         //If Match
	  if(ghostTextArray[i].startsWith(tokenVal)){					
		  editor.setGhostText(ghostTextArray[i].slice(tokenVal.length), position);
		  break;
	  };
  };
});

But what if i want to select the suggestion (By Pressing Tab)
Also how would i enable inline autocompletion as it's a part of ghostText?

Thanks
