# Hypertext Help with LaTeX
Styles

The following type style commands are supported by LaTeX. Note that LaTeX2e differs on this point, having instead a Font Selection scheme, but the following should still work (certainly in 2.09 mode).

- `\rm` Roman.
- `\it` Italics.
- `\em` Emphasis (toggles between `\it` and `\rm`).
- `\emph` (LaTeX2e emphasis command)
- `\bf` Boldface.
- `\sl` Slanted.
- `\sf` Sans serif.
- `\sc` Small caps.
- `\tt` Typewriter.

- `\boldmath` and `\unboldmath` (affects math mode fonts only)

These are LaTeX delcarations (with the exception of `\emph`), i.e., they do not act on an argument, but change the way LaTeX prints the following text. The scope of a declaration is ended by a right brace (`}`) or an `\end{}` command whose matching left brace (`{`) or `\begin{}` precedes the declaration.

Thus, for a short piece of italics or bold-face text one would use

      This is {\it italics} and this is {\bf in boldface}.

which would be set as "This is italics and this is in boldface.

In LaTeX2e the `\emph` command is considered more suitable for short stretches of emphasized text. A typical use would be

      This is \emph{emphasized text}.
