contenteditable - agrega una clase a un div actual

currentDiv es el div que tiene el símbolo de intercalación dentro
en un clic de botón necesito agregar una clase
problema: ¿cómo obtener qué div es el actual?

 $('button').on('click', function(){ $(currentDiv).addClass('indent'); });
 .indent{margin-left:30px;}
 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div contenteditable> <div>lorem</div> <div>ipsum</div> <div>dolor</div> </div> <button>CLICK</button>

Puede usar Range y la propiedad startContainer para obtener el elemento al que apunta el cursor:

 const contenteditable = $('[contenteditable]'); $('button').on('click', function(e) { var sel = window.getSelection(); var range = sel.getRangeAt(0); var elem = range.startContainer.parentNode; $(elem).addClass('indent'); });
 .indent { margin-left: 30px; }
 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div contenteditable> <div>lorem</div> <div>ipsum</div> <div>dolor</div> </div> <button>CLICK</button>
