You can leave the defaults unchanged or customize the following options:

* **Keyboard Shortcut**: The default is Command-9.
* **Action**: When pressing the keyboard shortcut from Mail or MsgFiler 4, you can choose from one of three actions to perform.

See how to customize these options [in this section](/using-msgfiler/msgfiler-shortcut.md).
