Here is the best setup (I think so :D) for K-series Keychron keyboards on Linux.

Note: many newer Keychron keyboards use QMK as firmware and most tips here do not apply to them. Maybe the ones related to Bluetooth can be useful, but everything related to Apple's keyboard module (hid_apple) on Linux, won't work. As far as I know, all QMK-based boards use the hid_generic module instead. Examples of QMK-based boards are: Q, Q-Pro, V, K-Pro, etc.

Most of these commands have been tested on Ubuntu 20.04 and should also work on most Debian-based distributions. If a command happens not to work for you, take a look in the comment section.

Make Fn + F-keys work (NOT FOR QMK-BASED BOARDS)

Older Keychron keyboards (those not based on QMK) use the hid_apple driver on Linux, even in the Windows/Android mode, both in Bluetooth and Wired modes.

Vim Cheat Sheet

Vim is an advanced CLI based text editor. Many key combinations used in Vim are easily associated with a memorable phrase. One effective way to use Vim is to associate phrases with Operators, Text Objects and Motions. Then compose a phrase for what you want to do. Start with an Operator followed by a Text Object or Motion. Prefix an Operator, Command or Motion with a number/count to extend it.
