In Mac OS X, how do I assign keystrokes to menu commands that don't already have them?

In Mac OS X, you can issue many commands from the keyboard without the aid of a mouse. These commands are often standardized. For example, simultaneously pressing the Command key and  q  almost always quits the application. In some cases, applications allow the user the option of changing which key combinations issue commands to the computer. Check the program's manual or Help menu for information about this option.

If there is no key combination for a certain command that appears in a menu, you can add one using Mac OS X's built-in keyboard shortcuts preference pane. To access it, from the Apple menu, select System Preferences... . In System Preferences, from the View menu, select Keyboard or Keyboard & Mouse, and in the preference pane that appears, select the Keyboard Shortcuts tab.
