Buttons

Buttons are simple. You click them with your mouse. If a button has an underlined letter in its label, you
can optionally hold down the Alt key and press the key that represents the underlined letter. For
example, as an alternative to clicking a button labeled Pattern, you can press Alt+P.
You might notice one button in a group has a slightly darker appearance than the others, such as the
OK button shown in Figure 2-10. That button is called the default button and, as an alternative to
clicking directly on that button, you can press the Enter key. Many dialog boxes also have a Cancel
button, which enables you to escape gracefully from the dialog box without saving any changes. As an
alternative to clicking the Cancel button, you can press the Esc key or click the Close (X) button in the
upper-right corner of the dialog box.
