In nearly all layouts £1 is configured to 0, then 50p 9, etc. I’d keep holds as 1 to 4. Collect is normally set as ‘. You can double up keys too, so often hi and lo can be set to the corresponding hold buttons. A lot of mine have cancel and collect in the same button too ie c and ‘ on one button. You’ll see mfme has this option. Once you are set on what you want, save the configuration. You can then load it in for each machine, saving time.
