Find it Fast
Ok, so you've opened numerous applications, documents, and Finder windows.  Your screen is cluttered and you need to switch to another application or find that other document you were working on.  No need to minimize or move windows, that's so old school.



By pressing a hot key or clicking on a specific area of the screen you can invoke Expose.  Mac OS X will darken the Desktop and highlight all open windows (un-minimized) and kick off a sleek animation.  All open windows and documents shrink into highlighted thumbnails and reposition themselves allowing you to see everything in clear view.  Another feature allows you to hide everything and  quickly display the Desktop.

Expose can be invoked to perform three actions with either a hot key or click of the mouse.  Some users refer to these as "Modes".

• All Windows
• Application Windows
• Desktop

Note that Mac OS X ships with default hot keys to invoke the actions but these can be configured.

All Windows
The "All Windows" action will work on all open windows and documents. By default, this action is invoked by pressing the F9 key.  You can click on any window/document to make the active window and application or hit the Tab key to cycle through all applications and their corresponding windows.  Just see how the Menu Bar changes.

Application Windows
The "Application Windows" action will work on the current active application to reveal all open windows/documents for that application.  Let's say you have five Safari windows open and you want to see them all.  Just hit the F10 key.

Desktop
The "Desktop" action moves all open windows and documents to the edges of the screen to display the Desktop underneath b pressing the F11 key.

Review - In a default Expose configuration:

• F9 tiles all open application windows
• F10 tiles all open windows for the current application
• F11 hides all open windows allowing you to view the Desktop

You can Customize Expose via System Preferences and change these keys.
