QuickBooks Online has an awesome mobile app you can use to conduct your business on-the-go! I know how important it is to be able to access tools quickly and easily. I'll explain further below.
The mobile app doesn't work through any shortcuts. You'll simply have to navigate the account manually by clicking the menu icons, and entering your transactions.
I hope this helps to address your question, but if I've missed the mark, please don't hesitate to reach back out or contact our support team.
