This allows you to switch between similarly-named Angular component files with an easy shortcut.
For example, if you have hello.component.ts open, you can activate this extension (press Ctrl+K, then Ctrl+O without ever releasing Ctrl) to tell VS Code to open hello.component.html. Activating it again will open the corresponding scss or css file. Activating it once more will open the corresponding ts file again.
