Ubuntu 16.04 LTS, Libreoffice 5.1.2.2:
I wonder where the “AutoCorrect Options” is? Or how can I turn off smart quotes? Thanks.
You will find the settings under TOOLS > AUTOCORRECT > AUTOCORRECT OPTIONS > LOCALISED OPTIONS > then deselect SINGLE and/or DOUBLE QUOTES.
You will find this documented under HELP > QUOTATIONS…Peter
