Fullscreen mode allows Terminal to use the entire screen.
This mode is useful if you have a device with limited screen space and
intend to work in Terminal for a long duration, or are working with
long lines of terminal output. It temporarily hides the window
decoration, allowing you to view more scrollback
lines on the screen.
To enable fullscreen mode:
Select View and check
Full Screen, or press F11.
The menubar will still be visible in fullscreen mode unless you have
hidden it.
If you have more than one Terminal tab open, the tab bar will
be visible in the fullscreen mode.
To disable fullscreen mode:
Select View and uncheck
Full Screen, or right click and select
Leave Full Screen. Alternatively,
press F11.
