Hi there,
Welcome to the Community. I'll be glad to steer you in the right direction so you can get back to doing what you enjoy the most.
The function you've described isn't available in QuickBooks. I recommend sending feedback about this to our product developers so it can be included in future updates. To do this, please click on the Gear icon > Feedback. In the meantime, feel free to check out the current: Keyboard shortcuts for QuickBooks Online.
Let me know if you have other questions by leaving a comment below. I'll be here.
