Object Zooming is a new feature introduced in Microsoft Word. It means while in the read mode we can zoom the objects like tables, chart or pictures by just double-clicking on them. The important point here is that during read mode we can zoom the images, tables or chart. The object zooming is useful when we want to see the objects larger. To close the popup just click outside the object and the object will return to its normal size.
