Author here. I was pointed to existing software solutions. There are for sure browser extensions. For macOS there is a (free) App [customShortcuts by Houdah](<a href="https://www.houdah.com/customShortcuts/" rel="nofollow">https://www.houdah.com/customShortcuts/</a>), which also is compatible with [KeyClu](<a href="https://github.com/Anze/KeyCluCask">https://github.com/Anze/KeyCluCask</a>).<p>What do you use? What am I missing.
