It is not enough to use the form <A|B>, I need the separate ket form |A>, which the math writer does not have since it insists that angle brackets exist only in pairs.

I can not use |A> = sum from and so on. It apparently does not know that the > is not part of the equals sign.

And I do not want to have to learn to use Tex instead of LibreOffice.

Thanks in advance.
