The author advocates for using 40% keyboards, arguing that reducing the number of keys improves ergonomics and typing efficiency. By mapping frequently used functions to a central 'home row' and utilizing layers, users can minimize hand movement and reduce strain, a method the author adopted after experiencing wrist pain in 2017.
Customization is central to this setup. The author uses Karabiner for macOS to manage key remapping and layers, writing configurations in Clojure via goku. Additional tools include VimiumC for browser control, Aerospace for window management, and Neru for mouse control, ensuring a consistent workflow across different devices and software environments.
For those looking to adopt 40% layouts, the author suggests starting by remapping individual keys before committing to specific hardware. Recommended accessible models include the plastic Epomaker th40 and the metal MMD-KM40, both of which support Bluetooth and 2.4 GHz connections and are configurable via Via.
Sourcing custom keyboards often requires exploring secondary markets like Avito, specialized Telegram groups, or Chinese platforms such as Goofish, which may require the use of intermediaries. The author also notes the use of Far East Gadget Typesticks to bridge the gap between external keyboards and laptop layouts.
