Is there an application in Tails where I can take a snapshot of the screen and save it? I have the print screen key on my computer, but am not sure if Tails has an application for it. I will check the applications again.
Yes, the printscreen key should work.
This can also be invoked through a program called "Screenshot", which provides the same functionality.
This is part of the core Gnome desktop environment which Tails uses.
From the Gnome user guide:
Open Screenshot from the Activities overview.
In the Screenshot window, select whether to grab the whole screen, the current window, or an area of the screen. Set a delay if you need to select a window or otherwise set up your desktop for the screenshot. Then choose any effects you want.
Click Take Screenshot.
If you selected Select area to grab, the pointer changes into a crosshair. Click and drag the area you want for the screenshot.
In the Save Screenshot window, enter a file name and choose a folder, then click Save.
Alternatively, import the screenshot directly into an image-editing application without saving it first. Click Copy to Clipboard then paste the image in the other application, or drag the screenshot thumbnail to the application.
