EVERY USER, EVERYDAY. QB's has done this for decades. Sage is so far behind in shortcuts. When I go to write an amount somewhere I should be able to add a list of numbers and hit enter. For example when I do a credit card payment and I break it down by accounts I want to be able to add all my fuel expenses off my CC bill in the fuel expense total box. Having to use a separate calculator adds time and mistakes. EVERYONE would use this everyday.
