+
+I recently got Logitech MX Keys for Mac keyboard at work.
+The German version, to be more precise.
+This version was three times cheaper than the Windows equivalent with either US or ES layout.
+Since I touch type anyway, I thought it was a bargain.
+
+As soon as I plugged it in, I realized there were some glaring issues with the keyboard.
+First of all, the Meta/Super and Alt keys are reversed in this keyboard.
+In the normal/full version of this keyboard, Logitech gives an option to choose between Mac, Windows and iOS host, and that changes the behavior of the keys.
+In this version, tho, only iOS and Mac are available.
+
+Besides that, there's the issue of the grave (tilde) and angle keys switched as well.
+
+Switching these keys around would be very easy with Xorg, but Wayland once again complicates things...
+
+These issues almost made me return the keyboard.
+Luckily, tho, there is another option: configuring the keys one level lower than wayland (and X11), through hwdb.
+
+Long story short, this will configure any Logitech keyboard with the same product id (0x4092) to use a saner configuration:
+
+
+```cfg
+#File: /etc/udev/hwdb.d/90-logitech-keyboard.hwdb
+
+evdev:input:b0003v046Dp4092*
+ KEYBOARD_KEY_700e2=leftmeta
+ KEYBOARD_KEY_700e3=leftalt
+ KEYBOARD_KEY_70039=leftctrl
+ KEYBOARD_KEY_70064=102nd
+ KEYBOARD_KEY_70035=grave
+ KEYBOARD_KEY_700e7=rightalt
+ KEYBOARD_KEY_700e6=rightmeta
+ KEYBOARD_KEY_7006d=compose
+
+```
+
+After that, simply run:
+
+```
+ sudo udevadm hwdb --update && sudo udevadm trigger
+```
