Shortcuts using fn don't work properly

Thank you,

It turns out that HotKey library that I use for global shortcuts doesn't support it soffes/HotKey#31

I see that skhd somehow managed to capture fn key koekeishiya/skhd#10 but, on my machine, it only works for built-in MacBook keyboard and doesn't work for the external Logitech keyboard. And skhd still has some limitations (like fn + arrows is not possible koekeishiya/skhd#10 (comment))

I will drop the fn literal from parsing to not confuse users, I will keep this issue open for now.

But honestly, I have no hope that it will be supported in the future

Workaround: since AeroSpace can be called from CLI, you can use skhd

I’d like to bring up support for fn again since the release of macOS 15.

In macOS 15, the usage of fn increased a lot. Indeed for a lot of system shortcuts, only fn from Apple keyboards are recognised. However, Karabiner has supported mapping any key to fn with support for all the new window layout shortcuts. I believe this is done by using the Apple vendor ID with their virtual keyboard device.

I’ve mapped a spare key to Apple fn on my keyboard. And I’d really like to be able to use that as my main modifier for all window management needs since I know it won’t conflict with any third party app.
