If your logitech keyboard is a fairly modern one [i.e. less than 2 years old].
It should send "multimedia" keys to Windows for all those special keys on your keyboard.
These are trappable by programs, however the program needs to be able to abvle to handle them.
[they are like standard keys though, so the same "multimedia key" on your logitech should send the same code as a similar key on say a Microsoft keyboard.]
There are many articles on Microsofts web site about how to remap these keys using Registry entries.
