there is key and entry with key between []

when sorting, the key wins but because there can be duplicates the entry 
itself is also part of the final sort key

the accumulates sort key is sanitized and after that sorting happens in 
several stages (these can be defined / adapted) according to language, 
taking numbers into account and finally using the unicode ordering ...

you can fool the system by messing with the [key]

it's not the easiest subsystem (but it has a long history ... as with 
many subsystems the principles are not much different than mkii and the 
code seldom changes but of course evolved)
