Not where I learned maths I always learned it as ]-π, π] and had never seen (-π, π] until this discussion cropped up. I find the former notation more intuitive and indicative of its meaning.

Re: 43S News
I was under the impression (at least from posts from the golden age, left elsewhere) that every key was reassignable in the 43s. Is it still so?
I wish you luck Jaco, however remember: left is right and right is wrong!

As usual, preference depends on what you learned first.

Re: 43S News
I think "]-π, π]" is referred to as "French notation" and "(-π, π]" is referred to as "American notation" or "English notation". I don't know about the rest of the world, but there is also "Czech notation" which is like American/English notation but replaces square brackets with angle brackets.

Same for me: I learned ] 0 ; 1] and the french wikipedia page https://fr.wikipedia.org/wiki/Intervall ... 9matiques) discreetly mentions:
meaningUne autre notation (d'origine anglaise mais très répandue également) utilise, pour les intervalles (semi-)ouverts, une parenthèse au lieu d'un crochet.
I find this "french" notation more intuitive.Another notation (of English origin but also very widespread) uses, for (semi-)open intervals, a parenthesis instead of a bracket.

Re: 43S News
Massimo, almost all can be changed in the USER menu, as also per Walter’s reference. But ‘EXIT’ bottom right is recommended not to change, i.e. that is a problem for left/right swap. Also I want the keys to permanently change, not while in USER mode only.

Re: 43S News
So that's four different notations so far. ISO 80000-2 only lists the (] and ]] styles (hooky scanned copy here).
Re: 43S News
The fact that I did my secondary and further education in France probably explains why I find it more intuitive too
