Currently my main editor is Visual Studio Code, which Microsoft has done a marvellous job on.
Despite installing various extensions for the various things I’m working with, I will collect some tweaks here that I usually do, so I can remember them later:
Navigate between tabs with Cmd+<number>
Add the Cmd+<number> keybinding to your keybindings.json file, as described in VS Code – Possible to switch tabs/files with cmd+numbers?
