Hi, I used all help files to get my vertical text orientation button to be usable, but I was never able to get it work. Does the function works or is it still in development? I tried to open all languages options etc. and it still does not work.
(3.5 Version and Windows Vista - I have enabled Asian Languages in Enhanced language support.)
Have you enable for Asian languages?
Menu/Tools/Options/Language Settings/Languages - Enhanced language support.
Also better to get help, if operating system and LibreOffice version is reported.
If you did activate Asian Language support, then you can configure vertical writing in Format|Page → Page → Textflow → "right-to-left (vertical)"
