Text Mate themes describe the theming rules used for syntax highlighting. Each rule consists of one or more scope selectors and a set of styles. To learn more about scopes and how they're used, check out the [color theme](https://code.visualstudio.com/api/extension-guides/color-theme) documentation.
You can directly use .tmTheme files in your extensions or import/convert them with VS Code's extension generator [yo code](https://code.visualstudio.com/api/get-started/your-first-extension).
- Open a file that has a language associated. The languages' configured grammar will tokenize the text and assign 'scopes' to the tokens. To examine these scopes, invoke the `Inspect TM Scopes` command from the Command Palette (`Ctrl+Shift+P` or `Cmd+Shift+P` on Mac) .
