Shimano mech limit screws: adjustment

Further to bicycle gear ratio analysis...

Aide memoire diagrams for which derailleur limit screw does what on which mech on which of our bikes. It's easy to forget as this is not done very often and there are so many different models of front and rear derailleurs. Even similar models; for instance on the FD-M590 and FD-M591 font mechs the limit screws are different ways round.
