+# Keychron K2 configuration on Linux
+
+## Function keys do not work
+
+To make the change permanent, [[Kernel_modules#Setting_module_options|set]] the `hid_apple` `fnmode` option to 2:
+
+#### `/etc/modprobe.d/hid_apple.conf`
+    options hid_apple fnmode=2
+
+## Switching Cmd and Alt/AltGr
+
+This will switch the left `Alt` and `Cmd` key as well as the right `Alt`/`AltGr` and `Cmd` key.
+
+Permanent change, taking place at next reboot:
+
+#### `/etc/modprobe.d/hid_apple.conf`
+    options hid_apple swap_opt_cmd=1
+
+You then need to [[regenerate the initramfs]].
