What does @before a function do in new Excel

[braindiesel]

I had a popup to explain this change in my formulas but accidentally closed it before reading it...
Can someone point me towards an explanation?

Example
=@IFS(AVERAGE(C14:E14)>=90,"A",A...

I have no idea, but try entering the formula in a different cell and see if you get the pop-up back.

I think we will see this question a lot as it has already come up once before in the last 24 hours (I'll bookmark the MS link ready).

Ignore that the title says ampersands

Thanks for pointing me the right way... I tried googleing @ function but that wasn't helping
