Had a bunch of markdown files with a frontmatter property I didn’t need any more, so I used this search expression in VS Code with regex enabled to find all lines starting with `booktitle:` and removed the entire line using replace with an empty string (tip: you can try patterns like this against sample text in my [regex tester](https://flaviocopes.com/tools/regex-tester/)):

```javascript

^booktitle:.*
```
