The function keys work by themselves.
So it must work for something else.
Thanks for reply.
That depends on
the keyboard and how it is configured.
I bought a
Logitech K780 which out of the box required you to
press the FN key if you wanted to use a function key
when using the keyboard with a Windows PC.
If you pressed a
function key without the FN key it would do system
functions like increase or decrease screen brightness,
turn the TouchPad on or off, raise or lower the
volume, mute the sound etc.
For example, in
Office applications F12 opens the older style Save As
dialogue or in Jaws the Jaws key+F11 speaks the time,
Jaws Key+F7 brings up a list of links on a webpage.
So, if I wanted
F12 I had to press FN+F12, if I wanted Jaws to speak
the time I had to press FN+Jaws Key+F11 etc.
Now, try pressing
the Jaws Key (Insert on the Numpad) and FN all the way
across on the left and then F7 to bring up a list of
links, maybe if your fingers are a foot long you can
I had to download
the Logitech Options application which allows me to
check a little checkbox which changed this so that
when I use the keyboard for Windows the Function Keys
just do what they should do without having to press
Now if I want to
press F1, F2 or F3 which are the keys which switch the
keyboard to my iPhone (F2) or Apple TV (F3) or if I
want to lower or increase the volume which is done
with F11 and F12 I have to press the FN key, but since
I don't do this as often I don't mind and if I press
F2 (when I use the keyboard for my PC I have to press
FN+F2) to switch to my iPhone then once it has
switched I don't need to press the FN key anymore
since the keyboard is smart enough to know when it is
connected to a PC or to an iPhone or something else.
got a new keyboard and it has a FM key.
does it do?
