## 13 Text Effects

### 13.1 Text

If you want to emphasise text, you can use the \emph{} command, which will emphasise the text in between the curly brackets, usually by putting it in italics. You can also specify this and other effects more directly:

• \emph{} emphasises text (usually italicised)
• {\em some_text } also emphasises text (usually italicised) but note the different placing of brackets!
• {\bf some_text } emboldens text but note the different placing of brackets!
• \textrm{} sets text in the normal Roman fount
• \textit{} sets text in italic typeface
• \textbf{} sets text in bold typeface
• \texttt{} sets text in the "teletype", fixed-width fount
• \textsc{} sets text in the "small capitals" typeface; everything will be in uppercase, but any capital letters will be typeset slightly bigger than the normal letters

### 13.2 Maths

In maths mode there are corresponding commands:

• \mathrm{} sets text in the normal Roman fount
• \mathtt{} sets text in the "teletype", fixed-width fount
• \mathit{} sets text in italic typeface
