Ability to use the + and - sign to change the date and add an invoice #, like we were to do in desktop version

I would like to have the option to use the + sign or the - sign when changing the date, instead of having to type in the date every single time we are posting a transaction. Same with invoice/cheque #'s - we used to be able to increase or decrease by 1 with the keyboard. Now we have to type everything in.
