/**
 * Keyboard provides an api for managing a virtual keyboard.
 * The high level api is {@link Keyboard."type"},
 * which takes raw characters and generates proper keydown, keypress/input,
 * and keyup events on your page.
 *
 * @remarks
 * For finer control, you can use {@link Keyboard.down},
 * {@link Keyboard.up}, and {@link Keyboard.sendCharacter}
 * to manually fire events as if they were generated from a real keyboard.
 *
 * On MacOS, keyboard shortcuts like `⌘ A` -\> Select All do not work.
 * See {@link https://github.com/puppeteer/puppeteer/issues/1313 | #1313}.
 *
 * @example
 * An example of holding down `Shift` in order to select and delete some text:
 * ```js
 * await page.keyboard.type('Hello World!');
 * await page.keyboard.press('ArrowLeft');
 *
 * await page.keyboard.down('Shift');
 * for (let i = 0; i < ' World'.length; i++)
 *   await page.keyboard.press('ArrowLeft');
 * await page.keyboard.up('Shift');
 *
 * await page.keyboard.press('Backspace');
 * // Result text will end up saying 'Hello!'
 * ```
 *
 * @example
 * An example of pressing `A`
 * ```js
 * await page.keyboard.down('Shift');
 * await page.keyboard.press('KeyA');
 * await page.keyboard.up('Shift');
 * ```

/**
 * The Mouse class operates in main-frame CSS pixels

 * @remarks
 * Every `page` object has its own Mouse, accessible with [`page.mouse`](#pagemouse).
 *
 * @example
 * ```js
 * // Using ‘page.mouse’ to trace a 100x100 square.
 * await page.mouse.move(0, 0);
 * await page.mouse.down();
 * await page.mouse.move(0, 100);
 * await page.mouse.move(100, 100);
 * await page.mouse.move(100, 0);
 * await page.mouse.move(0, 0);
 * await page.mouse.up();
 * ```
 *
 * **Note**: The mouse events trigger synthetic `MouseEvent`s.
 * This means that it does not fully replicate the functionality of what a normal user
 * would be able to do with their mouse.
 *
 * For example, dragging and selecting text is not possible using `page.mouse`.
 * Instead, you can use the {@link https://developer.mozilla.org/en-US/docs/Web/API/DocumentOrShadowRoot/getSelection | `DocumentOrShadowRoot.getSelection()`} functionality implemented in the platform.
 *
 * @example
 * For example, if you want to select all content between nodes:
 * ```js
 * await page.evaluate((from, to) => {
 *   const selection = from.getRootNode().getSelection();
 *   const range = document.createRange();
 *   range.setStartBefore(from);
 *   range.setEndAfter(to);
 *   selection.removeAllRanges();
 *   selection.addRange(range);
 * }, fromJSHandle, toJSHandle);
 * ```
 * If you then would want to copy-paste your selection, you can use the clipboard api:
 * ```js
 * // The clipboard api does not allow you to copy, unless the tab is focused.
 * await page.bringToFront();
 * await page.evaluate(() => {
 *   // Copy the selected content to the clipboard
 *   document.execCommand('copy');
 *   // Obtain the content of the clipboard as a string
 *   return navigator.clipboard.readText();
 * });
 * ```
 * **Note**: If you want access to the clipboard API,
 * you have to give it permission to do so:
 * ```js
 * await browser.defaultBrowserContext().overridePermissions(
 *   '<your origin>', ['clipboard-read', 'clipboard-write']
 * );
 * ```
