Use the Zoom In function (on the View menu) to magnify a selected region in a view. Zooming is like using a telephoto lens on a camera; it lets you focus on a specific part of a view by enlarging or reducing parts of the view. When you zoom in on a region, resource labels, such as icons and resource names, that were not displayed at the higher level may appear.
A new zoom level is created each time you use any of the Zoom functions. These zoom levels are stored for each view for as long as the view is open. To return to the previous zoom level, use the Undo zoom function.
To zoom in on a region, first select a region. You cannot zoom in on an individual object.
