• Normal. By default, the function keys perform tasks based on the operating system and application you're using. To use a function key in its normal state, you press it by itself

• Enhanced. The function keys are pre-programmed to perform certain tasks when you press them at the same time as the FN key (shown below). For example: F1 + FN launches your internet browser.

Using the Logitech SetPoint Mouse and Keyboard Software, you can change the pre-programmed function for each key. You can also swap the modes so the enhanced functions work without having to press the FN key. See the "Programming function keys" section of Knowledge Base article 20506 for instructions.

Here are the enhanced features of the F keys:

F1 = Launches Document application

F2 = Launches Spreadsheet application

F3 = Launches Presentation application

F4 = Launches Calendar application

F5 = Launches Internet browser

F6 = Launches instant Messenger application

F7 = Launches E-Mail application

F8 = Internet Search

To use the enhanced key functions, hold down the FN key and then press an F key.
