You missed diff, marker and expr.

You can remap zf to use custom function and emulate any behavior you need with fdm=expr. I guess you will have to rely on something like markers or signs to achieve what you want since simply recording first and last lines in a custom function and use this data within foldexpr will not work as when lines are added/removed simple records become invalid. Sign and markers position gets adjusted in this case though.

Tbh I have no real idea what you are talking about ;)

I just would like to select in visual mode some lines and fold them. Why should I record anything?

As usual, you should create a custom mapping.

I thought so but hoped for something built-in.

 

Thanks for your help :)
