+## udev
+This udev rule is credited to [Emilio Coppa](https://www.facebook.com/ercoppa) from the [Facebook: Keychron User Group](https://www.facebook.com/profile.php?id=534114427066453&ref=br_rs) and was provided as [GitHub Gist: ercoppa/80-keychron.rules](https://gist.github.com/ercoppa/87a42a5d1fd65539844d7badc276d8e7).
+
+1. Create udev rule `sudo touch /etc/udev/rules.d/80-keychron.rules`
+2. Add the udev rule `SUBSYSTEMS=="input", ATTRS{name}=="Keychron K6", RUN+="echo 0 | tee /sys/module/hid_apple/parameters/fnmode"` to `/etc/udev/rules.d/80-keychron.rules`
+3. `sudo udevadm control --reload-rules && sudo udevadm trigger`
+
+An alternative solution was offered by [Thạch Nguyễn](https://www.facebook.com/Cobblestone8x).
+
+1. Set fkeyfirst by:
+  - create the conf file `sudo touch /etc/modprobe.d/hid_apple.conf`.
+  - add this line to the file: `options hid_apple fnmode=1` and save
+  - `sudo update-initramfs -u`
+  - `reboot`
+2. Use the keyboard in Windows/Android mode
+
+
+## Numlock
+If you get stuck in Numlock mode, double tap fn2 + F6 to disable it.
+Alternative way is to open `onboard` and disable "NmLk" in there.
+
+## Battery
+The battery can report it's state via upower. If your distribution supports this you will be able to get a battery indicator on your desktop.
+
+To check the keyboard is recognized type:
+```
+$ upower --dump | grep keyboard -A 7
+```
+
+You can get some GUI front-end to reflect the battery status, and different distributions often have them enabled by default. Examples include `gnome-power-statistics`, `mate-power-statistics`, Arch with Gnome has battery reporting working out of the box and in Ubuntu `Settings ⇾ Power` it's also working.
+
+## Sleep
+The keyboard goes to Auto Sleep Mode in 10 mins of sitting idle to save battery.
+
+Press `fn1` + `S` + `O` (for 3 seconds) to disable the Auto Sleep Mode. If you want to go back to the Auto Sleep Mode, press `fn` + `S` + `O` (for 3 seconds) again. (Wait for the visual light confirmation.)
+
+## F Keys on Ubuntu
+
+There is a [discussion on Stackexchange](https://unix.stackexchange.com/questions/121395/on-an-apple-keyboard-under-linux-how-do-i-make-the-function-keys-work-without-t?fbclid=IwAR0cJUOhd6rRn3MG5lGK_3CGE73iy0nCFXqWrjjmtMVCeYjXLQdl7CzOn-E) regarding making the F Keys work.
+
+[Claus Zotter](https://www.facebook.com/claus.zotter) noticed the `F1` ⇾ `F12` keys always act as though `function` key is pressed.
+
+Edit (create if it doesn't exist, it doesn't on 16.04) `/etc/modprobe.d/hid_apple.conf` and add the line `options hid_apple fnmode=1` followed by:
+
+```
+$ sudo update-initramfs -u && reboot
+```
+
+If you want to test without rebooting, run `rmmod hid_apple && modprobe hid_apple`. Warning: If the Keychron K6 keyboard is the only input device, beware that doing so might leave your computer in an inoperable state unless hard reboot when the second command failes.
+
+> fnmode = 0 disable `fn` key
+> fnmode = 1 function keys are used as last key
+> fnmode = 2 function keys are used as first key

+* [Andrii Shkodyn Gist](https://gist.github.com/j2ko/00254950a24498df5902ddc9fceb5ee0) who also noticed he does not get a bind action on Ubuntu 16.04 but that it was working as expected on 18.04. (Seems of no issue with 1.6 in 16.04)
+
+## Keymap
+If your Keymap appears to be incorrect make sure that `/sys/module/hid_apple/parameters/fnmode` is set to `0` and not `1`.
+
+Method of binding `shift` + `delete` to `insert` suggested by [Konstantinos Liopetas](https://www.facebook.com/konliopetas).
+```
+$ xmodmap -pke | grep Delete
+My Output was:
+keycode 91 = KP_Delete KP_Decimal KP_Delete KP_Separator
+keycode 119 = Delete NoSymbol Delete NoSymbol Delete
+```
+So what I did was to add the following line on my `~/.bashrc` (to persist change on reboot)
+
+```
+xmodmap -e "keycode 119 = Delete Insert Delete NoSymbol Delete"
+```
+Reference: [Ask Ubuntu](https://askubuntu.com/questions/158333/how-to-create-a-shortcut-for-forward-delete/158524#158524)
+
+### Keymap: en-GB (United Kingdom) 
+When the keymap is changed to en-GB many characters useful for Linux administration and programming are hard to find. 
+
+The following is a list of the characters I have been able to locate on the changed keymap. The `\ |` describes the  key above enter on the Keychron K2. 
+```
+# = "\ |" 
+\ = AltGr + "\ |"  
+~ = Shift + "\ |"
+```
+I have not located `|`
+
+## Firmware
+Keychron are investigating [Linux Vendor Firmware Service](https://fwupd.org/) as a possible solution to delivering firmware on Linux, at present it is only possible to update the firmware via Windows.
+
+## Fast reconnect bluetooth
+For faster reconnect need to set "FastConnectable" to true in /etc/bluetooth/main.conf
+
+## GitLab
+
+[Мухаммад Алифф Муаззам](https://www.facebook.com/Tester2009) also maintains a [GitLab repository](https://gitlab.com/keychron/k2) that is dedicated to tracking issues with the K2.
