Opening LO Math (eg. via soffice --math), and its settings under Tools -> Options..., LibreOffice Math -> Settings, and comparing it to its help page reveals missing help for two options: - Enable visual editing - this was added in 24.2, when the visual editor was made non-experimental, but a setting was added for it instead (off by default for now); note that the whole feature isn't well-documented, see bug 159989, - Auto close brackets, parentheses and braces - see bug 43090, where it was added. https://help.libreoffice.org/latest/en-US/text/shared/optionen/01090100.html
