select multiple objects
An object is any item you place on a sheet, including images (photos), text boxes, shapes, tables, and charts. To select multiple objects, do one of the following:
Touch and hold one object on the screen, then tap the other objects with another finger. Use both hands if it’s easier.
Touch and hold an empty area of the screen, then drag the box that appears around the objects you want to select.
Note: If you’re working with inline objects, you can only edit one object at a time.
