Tabbing in QuickBooks Online Improved

I am a big fan of using the keyboard as much as possible and using the mouse to click only when easier. I spend a lot of time adding transactions from the Banking screen in QuickBooks Online and need to be time efficient. Previously, when tabbing through a downloaded transaction, if you started typing an account (or account number), it displayed the account (or all accounts that start with the first few letters you typed) in a dropdown menu and you would have to click the down arrow key to highlight the account you want and then the tab key. This was awkward and I usually just ended up using both mouse and keyboard.

I just discovered today (not sure when it changed) that I can now start typing an account (or number, as my accounts always have numbers) and QuickBooks Online auto completes the account it thinks I want to use in the field and shows a menu of it and other accounts above the field. If it is the account that I want, then I simply use the Tab key to confirm and move on to the next field. If I want to choose a different similar account, I can still use the up or down arrow key. What is nice about this feature is that it auto completes in the field and highlights the account in the menu above. 

The only problem I have tabbing is that when I reach the Add button, it doesn't change color like it does when you hover your cursor over it with a mouse. I would expect it to either highlight with a different color (currently, there is a very faint yellow outline that is very hard to discern around the green) or become surrounded with a black border/outline so that I know that this button is active. Then, I only have to hit the spacebar to click the button and add the transaction.

Now, if I can only start using these Keyboard Shortcuts. I guess it just seems like keyboard Twister having to use 3 keys [ctrl] + [alt] + shortcut key. It's like you have to figure out which hand (left or right) works best for the [ctrl] + [alt] combo depending on the shortcut key and its location on the keyboard and then practice a lot.
