"""
This is an adjusted version of the official simpletreemodel[1] that adds lazy loading and uses a dict as backend.

Instead of the dict it could also use a database or similar. Items are only loaded when expanded, which allows
for speedy startup-time, even with 2.5m items.

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.

Validating a Hex Value

/^#?([a-f0-9]{6}|[a-f0-9]{3})$/

Summary

A Regular expression, or Regex, is a method of validating a specific piece of text by use of a sequence of characters each including their own fundimental principles. Regex can be used to validate emails, hex values, URLs, and HTML. In this case we will be focusing on Hex values which are typically a # with 6 numbers or letters following it.
