Command in targeting a new browser window in notepad

I think there may be a bit of confusion here!

Notepad is a text editor, not a web browser. It's not capable of opening a new browser window or executing commands to target a new browser window.

If you're looking to open a new browser window or tab, you'll need to use a web browser like Google Chrome, Mozilla Firefox, Microsoft Edge, or Safari.

If you're trying to automate some task or script, you may want to consider using a scripting language like Python, PowerShell, or JavaScript, which can interact with web browsers and perform tasks like opening new windows or tabs.

Let me know if you have any further questions or if there's anything else I can help with!
