Choose a font style from the Font Style menu in the Character palette or options bar.
If the font family you chose does not include a
bold or italic style, click the Faux Bold button or
the Faux Italic button
in
the Character palette to apply a simulated style. Alternatively,
choose Faux Bold or Faux Italic from the Character palette menu.
Use a dynamic shortcut. Dynamic shortcuts are keyboard shortcuts that are available (in edit mode only) for Faux Bold, Faux Italic, All Caps, Small Caps, Superscript, Subscript, Underline, and Strikethrough.
