The VS Code Superpower You Aren't Using Enough

If you find yourself renaming variables or changing repetitive strings one by one, you're wasting time. The single most powerful editing feature in VS Code is multi-cursor selection. You can hold down Alt (or Option on Mac) and click everywhere you need a cursor to appear. Alternatively, use Ctrl+D (or Cmd+D) repeatedly to select the next matching instance of your current selection. Instantaneous parallel editing turns tedious refactoring into a two-second task.
