Nicely put.

I did install 26.3 to make sure, and I've checked again and I
genuinely can't see that, but if it does, sorted, thanks.

The \= I'm sure is great, I just don't know where it might be useful.
Some examples might be of help however the manual isn't the place for
them.
The value of other anchors is obvious, I've used them all IIRC.

Thank you all.
