Emphasis

You can use bold and italic to emphasise text, although you cannot combine these to give *bold-italic* – the text will appears as bold surrounded by stars, but not italic. See Custom Styles for a way to do this.
You can also use a star before/after some text to make it italic (*italic*), and a double star to make it bold (**bold**). (You can also use the back quote to delimit text you would like to have in italic).
