Hi Fran,

First make sure your whole model is selected.

If you click on the hand  (1.) next to the word Global (2.) you will see three icons. If you click on the donut icon (3.) a wigit wll appear over your model. (4.) The wiget is colored red blue and green. Clicking on one of those circular lines and draging will rotate your model.

Your lolipop on  a stick is  your light which can be edited by selecting it but only in object mode.
