Are there shortcut keys in Mac to navigate to a button?

Question

Usually the dialog has 3 buttons - Cancel, No and Okay. In Windows, I can do Alt+O to select Okay. How to do this in Mac?

Answer 1

Escape selects cancel buttons and return (↩) selects OK buttons. ⌘⌫ or ⌘D often selects buttons like Don't Save. Enter (⌅ or fn-return) selects a default button when the focus is on a multi-line text field (like in some crash report dialogs).

If you enable full keyboard access from the keyboard preference pane, you can focus buttons by pressing tab.
