This is one of my favorite keyboard shortcuts, especially as fonts seem to be getting smaller and smaller… Or am I just getting older? In any case, here is the shortcut:
Zoom IN: CTRL + +
Zoom OUT: CTRL + –
Return to Original Size: CTRL + 0
To use any of these keyboard shortcuts, hold down the CTRL key on your keyboard (or the Command key on a Mac) and then type the other character. EXAMPLE: To Zoom in, hold down the CTRL (or Command) key and then type the “+” key.
What I really love about this shortcut is that it works on web pages – bye-bye, teeny-tiny fonts! (One exception: it doesn’t work on Internet Explorer 6, only the newer versions). It also works in Photoshop and Photoshop Elements, which can be a big help when you are working on fine details of graphic images.
