Where is AutoCorrect Options?

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
