When you enter text, LibreOffice automatically recognizes a word that may be a URL and replaces the word with a hyperlink. LibreOffice formats the hyperlink with direct font attributes (color and underline) the properties of which are obtained from certain Character Styles.
The following texts are changed to hyperlinks:
http://x, https://x, www.x.x
file://x, ftp://x, smb://x
where x is one or more characters.
If you do not want LibreOffice to automatically recognize URLs as you are typing, there are several ways of turning off this feature.
When you are typing and notice that a text has just been automatically converted into a hyperlink, press+Z to undo this formatting.
