how can I remove auto format text

Hello, I have LibreOffice Writer problem.

It seems to consider that whenever I use a slash I mean to style the text in italics and whenever I use several - in a string that means I want strikethrough. Also it keeps adding uppercase on the beginning of lines.

I like to use writer to keep a journal of my admin actions on a server with lines such as
useradd -g sftp_users -d /upload -s /sbin/nologin webUploader

How can I get writer to just leave my text alone ?

Thank you

Try menu Tools > AutoCorrect → uncheck While Typing
