# Mouse class
The Mouse class operates in main-frame CSS pixels relative to the top-left corner of the viewport.
#### Signature:
```typescript
export declare class Mouse
```
## Remarks
Every `page` object has its own Mouse, accessible with \[`page.mouse`\](\#pagemouse).
The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Mouse` class.
## Example 1
```ts
// 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 [\`DocumentOrShadowRoot.getSelection()\`](https://developer.mozilla.org/en-US/docs/Web/API/DocumentOrShadowRoot/getSelection) functionality implemented in the platform.
## Example 2
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>', ['clipboard-read', 'clipboard-write']);
```
