You can use a variety of fonts in TextEdit, and you can change the way they look. You can use the Styles pop-up menu in the ruler to choose common text styles, or you can use keyboard shortcuts (such as Command (⌘)-B for bold text).
Some fonts have special characteristics, such as ligatures or character shapes, that you can add to letters. Special characters, such as the copyright symbol or graphics arrows, may also be available.
Plain text documents cannot contain formatting.
To quickly select a commonly used font style, such as bold, select some text and choose the style from the Styles pop-up menu in the ruler.
If you don’t see the ruler, choose Format > Text > Show Ruler.
To customize the appearance of the font, select some text and choose Format > Font > Show Fonts. In the Fonts window, select a font and style in the Family and Typeface columns. Select a font size in the Size column or use the slider to change the font size.
To change the font color, select some text and choose Format > Font > Show Colors. Then select a color in the Colors window.
If your font uses special ligatures, add them by choosing Format > Font > Ligature.
If your font has special character shapes available, add them by choosing Format > Font > Character Shape. Then select or deselect Traditional Form.
For access to more special characters, choose Edit > Special Characters.
After you’ve selected the settings you want, you can save those settings as a style that appears in the Styles pop-up menu.
