Bold — Embolden the selected text, or disembolden it if it's already bold.
Italic — Italicize the selected text, or unitalicize it if it's already italic.
Underline — Underline the selected text, or remove the underline if there already is one.
Bigger — Step up the font size of the selected text.

Show Colors — Show the Mac OS X Colors panel, where you can select a color, then drag a color swatch onto text, task bars, or entries in the Project Styles inspector.
Copy Style — Copy the style of the selected text, so that you can apply it elsewhere with the Paste Style command. This uses a special style clipboard, so you don't lose the data in the normal clipboard.
