It raised my hopes momentarily and then I saw the word 'keyboards' and my super swift brain instantly figured they'd put that in in order to distinguish from the well known 'hammond organs' which one would think of without needed any calculation whatever, the very word 'hammond' being synonymous with 'organ' - it otherwise being a redundancy if they meant to simply refer to the fact that an organ has a keyboard.
My super swift super brain frequently leads me astray..... that's why I don't use it often.... much friendlier to ask people, they're so much more reliable and pleasant, helpful....
