Hi. I have to say I really enjoy the "AFB set" shortcut for the Vectron, i.e. for me on PlayStation the combination of the SQUARE and UP keys to confirm the new AFB speed. In order to make LZB end procedures for many locos easier, how about a combination for AFB reset. This would mean that pressing that combination sets AFB first to zero and then the last selected speed. This would reset the AFB, as is required after LZB end. On PlayStation, this could for example be the SQUARE key and DOWN.
