How to switch of Writer to change '/word/' to word in intalic without '/'?

When I need to write in LibreOffice Writer a lot of texts with networking explanations including examples of code in the text. But when I wrote some thing like “:/home/user/file” Writer automatically changes it to “:homeuser/file” where the word home become written in italic letters.
Also in some official documents I need to have words surrounded by ‘/’ and Writer is changing them to same words in Italic letters without the ‘/’.
How can I switch off this?
I suspected it may be auto text functionality but could not found it there?
