Keyboard Maestro is an app that allows to automate tasks within macOS. Think: Shortcuts on steroids.
I call the Keyboard Maestro macros with hotkeys, from Stream Deck or with an extension for Raycast, but some triggers can be automated as well, eg. connecting an USB device.
Things I automate 
- copying currently opened URL in Markdown format
- copying samples to my MPC Live once I connect it to my computer
- googling the selected text with ⌘ ⇧ 1
- opening Google Maps with the route and ETA to provided destination
- text expanding and manipulation - e.g. by typing ;invoiceI make KM to type full message of my typical invoice e-mail
- typing ;phpto include<?php ... ?>
 
- e.g. by typing 
- translating the selected text
- opening my favorites directories in Finder from everywhere
- etc. etc.
Even though these examples are basic, it feels right to automate these activities. I've learnt a lot about the application itself when I was making these scenarios.
Useful shortcuts 
- ⌃ + ⌘ + A- Insert Action by name
Text expander fix
