### Adding and modifying user shortcuts

Shortcuts enable you to perform tasks quickly. They eliminate the need to click an icon, select a menu option, or carry out a series of steps.

You can define shortcuts or modify shortcuts for your personal use. However, any definitions or modifications you make to shortcuts do not persist after you end your Disc Advanced Viewer session.

For a list of tasks that can be performed using shortcuts, see Available shortcuts.
