The F8 Key Isn't Working Correctly

In Mac OS X, the F8 key and Ctrl+arrow key combination are reserved for triggering Spaces (a feature that lets you organize your windows on multiple desktops). Because of this, the F8 key and Ctrl+arrow key may not function correctly with Windows programs.

If you are experiencing this problem, change the Spaces hotkeys settings. See Mac Help for more information. From the Finder, choose Help > Mac Help or Help > Help Center and search for "Spaces."
