To apply a type style to selected text, do one of the following things:

• Choose Style > Type Style and choose a type style from the submenu.
• Choose Style > Character and click check boxes in the Type Style area.
• Choose a type style from the Text Styles drop-down menu in the Measurements palette. Apply bold and italic type styles using the icons to the left of the Text Styles drop-down menu. To remove all styles from selected text, choose Remove All Styles from the Text Styles drop-down menu.

Intrinsic fonts are distinct font styles built into font families, such as “Times New Roman MT Std Bd” in the “Times New Roman MT Std” font family.

Simulated fonts are plain intrinsic fonts that have been modified to simulate bold, italic, or bold italic. When a font family does not include a bold or italic variation as a separate intrinsic font, you can apply the bold and italic type styles to allow your operating system to perform a transform to create a bold or italic rendition of the font. The result is a simulated font.

When you apply bold to a plain font, the application first tries to find an intrinsic bold version of the font, and then if it can’t find such a font, it creates a simulated bold version of the font.

Warning icons identify simulated fonts in a layout because simulated fonts can cause output problems. Simulated fonts display with a warning icon in the Measurements palette, the Glyphs palette, the Character Attributes dialog box, the Style > Type Style submenu, the Edit Character Style Sheet dialog box, the Change To area of the Find/Change palette, the Fonts pane of the Usage dialog box (Utilities menu), the Replace Font dialog box accessible from the Usage dialog box, and the Character Attributes tab of the Rubi dialog box.
