With some effort, I actually was able to get the function
keys to work the way I want them to.
I had to go into the Logitec Options software that I
installed when I activated the keyboard and check a box that said something
like use the standard function keys.
Once I did this, I was fine.
The Windows function keys now work normally as they
If I want to do something like switch to another device,
raise or lower the volume level, etc., I simply have to hold down the FN
key on the keyboard and then use the function key I need for what I want to
So, all is well now.
I wish I had bought one years ago, and at yesterday’s price
of $39 US, it was an excellent bargain.

Subject: Logitec K780
I originally wanted to write off list to Sieghard, but
can’t seem to retrieve his personal address from the below e-mail, so I’ll
certainly welcome anyone’s response.
I have successfully paired my Logitec K780 keyboard with
my new Windows 10 laptop via bluetooth, and also have paired it wirelessly
with my older Windows 7 computer via the dongle that was provided with the
To those of you who have Logitec K780 bluetooth
keyboards, I have a question, though:
As we know, the function keys on the top of the Logitec
K780 are used for many different functions, including selecting the devices
to which the keyboard is paired, controling the volume level,
The only way I can convert those function keys to the
standard Windows function keys (F1 through F12) is to hold down the FN key
on the lower lefthand corner of the keyboard. This can become rather
awkward when, for example, closing a Word document with Control F4 or
closing an app with Alt F4.
We installed the logitec options software, but that has
not solved this issue.
Is there any way to lock in the function keys so they
remain the standard windows function keys, so I don’t have to press the FN
key whenever I want to do something involving those standard Windows
function keys? I can do this on my Windows 10 PC by toggling them on or off
via the FN and escape keys.
Thanks for any assistance.
If you want portable/compact the Logitech K780 is
probably your best choice. It’s heavy because it’s made heavy since you can
stand an iPad up in a channel which runs across from left to right above the
function keys, but while it has a full numeric pad, it’s still fairly
compact because it does not have the big gap you find on a full-size
keyboard with the 6-pack and inverted cursor T. The K780 actually has the
inverted cursor T, but it’s underneath the right shift key, think of the
shift and enter key being the width of 3 other keys so the left arrow, down
arrow and right arrow take up the same space as the shift key and in height
the down arrow and up arrow above it are I think also the same height as the
The nice thing with this keyboard is that it is a
Bluetooth keyboard, but it also comes with Logitech’s tiny unifying USB
receiver so if you have a computer without Bluetooth (most likely your
Windows 7 computer won’t have it), you can plug in the little dongle and use
your Windows 7 PC that way and you can pair your Windows 1 PC which
hopefully has Bluetooth via Bluetooth.
You can pair up to 3 devices with that keyboard so you
could even pair it with your iPhone as a third device and all you have to do
is press F1, F2 and F3 to switch between device 1, device 2 and device 3.
The one issue is that the function keys will not work as
regular function keys unless you install the Logitech Options software where
you can change this. It’s not a very accessible install, but if you have
sighted help it only takes a minute or less and once installed and once you
check the little checkbox to use the function keys you can just forget about
If you do this then on a Windows PC you have to press FN
along with F1, F2 or F3 to switch devices, but if, for example FN + F3
switches to you riPhone, then in order to switch back to one of your Windows
computer you only press F1 or F2 since iOS won’t require the FN
