The F-keys at the top of your keyboard have enhanced functions. If you want them to act like standard F-keys, and only access the enhanced mode when you press the Fn key, you can use Logitech Control Center (LCC) to make them behave this way by default.

NOTE: You need Logitech Control Center 3.60 or later installed to do this. To get the latest software, see answer 31561.

To enable standard F-key function:

1. From the Apple menu, select System Preferences.

2. Click the Logitech Control Center icon.

   

   The Logitech Control Center window will appear.

3. Click once on the keyboard you want to configure, and then click Configure.

   

4. Select the check box next to "When this box is checked, press F1, F2, etc. keys to use the standard function keys…"

   

5. Once you choose this option, the changes are automatically saved. You can test your F-keys and close the window.
