* Keyboard provides an api for managing a virtual keyboard.

|
||
* 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.
|
||
*

* See {@link https://github.com/puppeteer/puppeteer/issues/1313 | #1313}.

|

* ```ts
|
||
* await page.keyboard.type('Hello World!');

* await page.keyboard.press('ArrowLeft');

* await page.keyboard.press('Backspace');
|
||
* // Result text will end up saying 'Hello!'

* // Using ‘page.mouse’ to trace a 100x100 square.

* await page.mouse.move(100, 0);

|

|
||
* **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:
|
||
*
|
||
* ```ts
|
||
* 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:
|
||
*
|
||
* ```ts
|
||
* // 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:
|
||
*
|
||
* ```ts
|
||
* await browser
|
||
* .defaultBrowserContext()
|
||
* .overridePermissions('<your origin>', [
|
