To delete text:
|Click a text object. Or select multiple objects by dragging the mouse over them.
|Hit the key.
If you are already "inside" the text object, that is, editing text within it, then the key will only remove the character immediately after the text cursor. If you are already editing text inside the object and decide to delete the entire text object, then unselect the text object first. Then follow the above procedure for deleting the text object.
