There are two buttons on the left of the Moonwriter. The left button
is used to transport the paper, the right of the two buttons is the write button.
To the right is the flat writing square with straight and circular indentations.
Above the writing square, a lever with a ring as a finger holder protrudes
from the device.
To write, the writing button must be pressed while inserting your finger
in the hole in the lever above the writing square and tracing the corresponding
moon letters on the
writing square along the indentations.
