To refer to GNOME applications:
- Use their short name as it appears in the menus when giving
instructions to be executed inside Tails.
*For example*:

- Prepend "*GNOME*" when giving instructions to be executed outside of
Tails.

- **persistence feature**
To refer to the features available in the configuration of the
*persistent volume*.
- *For example*: when the Additional
Software persistence feature is activated.
The word *persistence* can be omitted if it is redundant from the context

the *Boot Loader Menu*.
* *For example:* Adding `radeon.dpm=0` to the [[startup
