MATLAB desktop keyboard shortcuts, such as Ctrl+S, are now customizable.
 In addition, many keyboard shortcuts have changed for improved consistency
 across the desktop.

 To customize keyboard shortcuts, use Preferences. From there, you can also
 restore previous default settings by selecting "R2009a UNIX Default Set"
 from the "Active settings" drop-down list. For more information, see Help.
