/**
* 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, 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']
* );
* ```
