I made a shortcut with Automator to open a file with VS Code in Finder. But I can't assign it to the desired keyboard shortcut (command + option + c) because it is already taken by 'Copy "filename" as Pathname' shortcut. I can't reassign in System Preferences -> Keyboard -> Shortcuts -> App Shortcuts because it has a variable name in it.
Here is how I used the control + command + c keys in Keyboard Maestro. It's a paid app with a free trial period. Frankly, I didn't have much luck defining apple's keyboard short cuts. It was all confusing to me.

Keyboard Maestro does come with an assist to help you create your first action. It's a little confusing at first to figure out what button to click when. They do have a forum.
