Italic text is also used for emphasis, and is conventionally used for the names of works of art, books, and other creations rather than enclosing them in inverted commas.
To italicise text follow the process described above for Bold, but use the Italics button or enter Ctrl-I (RISC OS).
To revert to normal text from bold or italic, select the text you want to change. The bold or italic button will be selected: click on it to turn the setting off and the selected text will revert to being plain text.
