To quickly get the “big picture” you may need to see the whole slide or image. There are some great keyboard shortcuts to do this, but they are different in PPT 2003, PPT 2007 and Photoshop.
PowerPoint 2003:
Option 1: Use the drop-down menu and choose FIT
Option 2: Install the PPTools free StarterSet and click the magnifying glass icon
PowerPoint 2007
Click the ‘Fit to Window’ button in the lower right corner
Photoshop:
CTRL + 0 (zero)
