windows - Disable Surface Pro 4 Type Cover Fn key toggle behavior

The Surface Pro 4 Type Cover has a "Fn" key that can be toggled on and off, which switches the behavior of the top row of keys from F-keys to utility keys like turning the volume on and off.

I use the Fn key very often while text editing (Fn+arrow keys), and I end up toggling the Fn key on and off over and over again as I'm in the midst of typing. I use the F-keys a lot as F-keys, so I'm constantly accidentally turning my volume on and off when I press alt+F4. This is really getting on my nerves.

I'd like to disable the Fn toggling feature entirely. Instead, I'd like it to stay "always on", in such a way that the F-keys always behave as F-keys, while still allowing me to use the alternate functions by pressing the F-keys while holding down Fn. Is this possible? Cheers.

Answer

I don't believe that exactly what you're asking for is currently possible, no. I found some discussion and suggestions in this thread (along with many people who did not understand the question!) which may help you solve your underlying problem in other ways though.

One suggestion there was to use AutoHotKey to map the F keys permanently to their desired functions - F1 for Help, F5 for Refresh etc. I haven't done this myself, but have used AHK before and recall it being fairly straightforward.

However, probably the easiest solution is to either:

• Buy an earlier Type Cover (from a Surface Pro 3 for example), where the Fn key required you to also press Caps Lock to toggle between the two behaviours, making an accidental toggling almost impossible (unless you play your keyboard like a grand piano!) or at least much less likely.


• Alternatively, you could get an inexpensive USB/Bluetooth keyboard which doesn't have the Fn toggle functionality at all and use that instead of the Type Cover.
