+As a follow-up to my last post, I've decided to also configure my mk850 combo (k850 + m720 triathlon).
+
+Some notes:
+* The keyboard is usually connected to this PC through bluetooth. Since this is a change I usually do in the system for every keyboard, I added a rule for any bus (usb, bluetooth, etc)
+* The mouse has an additional button that registers as a keyboard. Every press maps to three key events. I've disabled two of them and mapped the action to F19, in case I want to use it in my DE/WM.
+
+```cfg
+evdev:input:*                                                        
+ KEYBOARD_KEY_70039=leftctrl  # bind capslock to w 
+
+evdev:input:b0005v046DpB015*
+ KEYBOARD_KEY_700e0=f19
+ KEYBOARD_KEY_700e2=unknown
+ KEYBOARD_KEY_7002b=unknown
+
+```
+
+After that, simply run:
+
+```
+ sudo udevadm hwdb --update && sudo udevadm trigger
+```
+
+Make sure the settings have been applied by running `evemu-describe`:
+
+```bash
+ sudo /sbin/evemu-describe  /dev/input/event<id of your device> | grep KEY_  
+```
