is there a way to, on an online video, copy the screen? I am watching a direct instruction for schoolwork and don't know if i can, can I?

You can halt the video, and use "snip" (if you are using Microsoft Vista or Windows 7) to copy the screen. Depending on you viewer, you could also take snapshots of the clips.

Yes, there is a way to copy the screen while watching an online video. You can take a screenshot of your screen to capture the image or content displayed. Here's how you can do it on different devices:

1. Windows:
- Press the "Print Screen" (PrtScn) key on your keyboard. This will capture a screenshot of your entire screen.
- Open an image editing program such as Microsoft Paint.
- Paste the screenshot by pressing "Ctrl + V" or right-clicking and selecting "Paste".
- Save the image by clicking "File" and then "Save".

2. Mac:
- Press "Shift + Command + 3" together to capture a screenshot of the entire screen.
- The screenshot will be saved on your desktop as a .png file.
- Alternatively, you can press "Shift + Command + 4" together and then click and drag to select a specific area of the screen to capture.

3. Mobile devices:
- On most Android phones, you can press and hold the power button along with the volume down button simultaneously to capture a screenshot.
- On iPhones, press and hold the side button (or the home button for older models) and press the volume up button at the same time to take a screenshot.
- The captured screenshots are usually saved in your Photos or Gallery app.

Please note that the steps above may vary slightly depending on the make and model of your device or operating system.
