The F7 and F8 keys may be used to toggle between different display modes, such as full screen or windowed mode. Additionally, some function keys can be used to open specific programs or websites. For example, the F11 key is often used to open a web browser, while the F12 key may be used to open a file explorer.
If you are unsure about the specific functions assigned to the function keys on your laptop, you can refer to your laptop’s user manual or documentation.

Troubleshooting Function Key Issues
If your function keys are not working, there are a few possible causes:
1. Software Issue
Sometimes, a software issue can prevent function keys from working properly. To fix this, try restarting your laptop. If that doesn’t work, you can try updating your keyboard drivers.
