What do the F keys do on my K3500 keyboard

What do the F keys do on the K3500 keyboard when I'm NOT in any particular program, just in Windows in general?  I can't find any info anywhere on what the various icons mean.

From the following image

 

I can see it is a standard keyboard. Below are some common uses for function keys in Windows:

• F1 - Display help screen
• F2 - Highlight file or folder for renaming
• F3 - Open search tool
• Alt+F4 - Close the current window
• F5 - Refresh the contents of a window or webpage
• F8 - Boot Windows into Safe Mode by holding F8 during startup

Regards.

Thanks, Banhien, but what I was looking for is the meaning of the Fn icons.  I finally found it by searching for “Win8 Fn keys”.
