    ### What is a bookmarklet?

    > a small software application stored as a bookmark in a web browser, which typically allows a user to interact with the currently loaded web page in some way.
    That is, when the URL field of a bookmark contains JavaScript. This one is for printing internal docs to PDF by simply clicking on a bookmark:

    ```javascript
    javascript: (() => { let auth_num = document.body.outerHTML.match(/NMED\d{9}/g); let datetime = new Date().toJSON().replace(/[^a-zA-Z0-9]/g, '_'); document.title = `${datetime}_${auth_num}`; window.print(); window.close(); })();

    ```

    ### Breaking it down

    #### 1. The bookmarklet JavaScript template

    ```javascript
    javascript: (() => { /* add arbitrary code here */ })();
    ```

    #### 2. The "inner" JavaScript

    ```javascript
    // These parts are irrelevant as they
    // are specific to internal HTML documents.
    let auth_num = document.body.outerHTML.match(/NMED\d{9}/g);
    let datetime = new Date().toJSON().replace(/[^a-zA-Z0-9]/g, '_');

    // Change title of the HTML document as this
    // will be the default name of the printed PDF.
    document.title = `${datetime}_${auth_num}`;

    // Open print dialog (same and CTRL+P).
    window.print();

    // (Optional) Close the browser tab.
    // Only works if that has been opened programmatically!
    // (Such as using Vimium plugin in Chrome.)
    window.close();
    ```
