This is my custom keyboard bindings and arguments to use with PasteFlow, a paste stack for Alfred that helps pin and reuse text, files, and more. My configuration is a work in progress that I often tweak, so you can always find the most up-to-date version at THIS LINK (just search for "pasteflow").

I use Karabiner Elements, a powerful keyboard customization tool for macOS that lets me create layers and sub-layers, similar to having multiple keyboard layouts that activate with different modifier keys. This gives me unlimited possibilities for triggering different actions with just a few keystrokes. If you're using a mechanical keyboard, you can achieve similar results with firmware like QMK or VIA.

In my setup, I use Caps Lock as the main layer key, with additional S and E sub-layers. I configure these key bindings using Goku, which makes setting up Karabiner much easier through a simple configuration file. Since I usually keep my left hand on the keyboard (with my right hand occasionally on the mouse), I've designed all PasteFlow shortcuts to work with just the left hand. While this setup might not suit everyone's needs, the following table might give you some ideas for your own keyboard customization.
