TYPO3 Core

Original text:

This page: https://docs.typo3.org/typo3cms/ViewHelperReference/typo3/fluid/latest/CObject.html explains currentValueKey with currentValueKey, which does not provide too much insight...

Also, according to a Slack comment, a construct like this should also be possible:

> <f:cObject typoscriptObjectPath="lib.someLibObject">{someValue}</f:cObject>

But it is not documented here.

I'd like to provide my own explanations - but unfortunately I have no clue what this currentValueKey is good for. Hopefully I can encourage somebody to provide some explanation and maybe 1 or 2 examples. I'd be happy to review!
