What do the function keys mean on Dell Latitude E6230?

I checked all the manuals, and online ... to no avail. Thanks!

Normal function keys (F1 .. F12) when pressed by themselves, special control -e.g. volume control, turning WiFi On/Off, mirroing of the screen, etc (indicated in blue) when pressed with <Fn>.
