gco() should return the handle of the currently selected object. Selecting is just a matter of clicking (once) on the object. Recognizing the delete key would be done by setting KeyPressFcn callback for the figure: be sure to check the event data to be sure the proper key was pressed. It might also be a good idea to get() the Type of the current object and check it, so that you only delete the kind of objects you want.
