Tip #1 - Did you know when you hold down the control key and the A key at the same time in Quicbooks that your Chart of Accounts will automatically open up? This can save you time over the course of the day because you don't have to use your mouse to navigate to the drop down menu.
Tip # 2 - When you are in a transaction or the items list, if you hold down the control key and the letter N, it will bring a new transaction or list item window up automatically. Again this will save you time because you do not have to take your hand off the keyboard, find your mouse and then navigate to the appropriate drop down.
Tip # 3 - Press the control key plus the letter I to create a new invoice.
