Taking a screenshot

To take a screenshot of the entire screen, part of the screen, or a single window choose Applications ▸ Screenshot.

You can also press the PrtScn key of the keyboard to take a screenshot of the entire screen instantaneously. The screenshot is saved in Places ▸ Pictures.

Recording a screencast

To take a screencast:

Press the key combination Ctrl+Alt+Shift+R.
A red dot appears in the system menu near the top-right corner of the desktop when recording starts.
Press again the key combination Ctrl+Alt+Shift+R to stop the screencast.
The video is saved in Places ▸ Videos.

Unfortunately, this screencast has no sound and more complete applications like Kazam stopped working in Tails 5.8 (December 2022). Tails 6.0 (mid 2023) should integrate better screencast features. (#19441)

Until then, you can record the sound with Sound Recorder.
