Ok, so ive had the EZ-Command (original one) for a couple of years, and ive known about being able to turn the lights of locos on/off with no 10 in function mode. The question is what do the other ones control? Ive just notice with one of two locos i have (it has a Lenz Gold Mini Decoder fitted), that no 3 reduces its top speed considerably, and no 4 changes the speed at which it decellerates/accellerates. Do the others do anything? if so what, ive randomly clicked them but got no response from them.
Also my second loco has a TCS M1 in it, and the only function button that does anything is no. 10. Im guessing that is just to do with the decoder (what it is capable of).
