In its day, the concept of overlapping windows on the screen was brilliant, innovative, and extremely effective. (Apple borrowed this idea from a research lab called Xerox PARC.)

You’ll have to fight your way through 50,000 other windows on your way to the bottom of the “deck.”

A second Exposé keystroke is designed to help you find a certain window only ...
