In the selection area above the key input field you
can decide to enter the key in a direct way (keyboard; see direct key) or to read the key using a key dataset. Using a parameter dataset, you can
additionally generate a random key by mouse moves.
Overlay information are only used if the
corresponding checkbox field “with overlay information” below the initial key
input field is switched on.
It’s useful especially having “long” keys to work with
key datasets or overlay
datasets in direct mode to get approximately the entire range of keys being
possible (see also common key information).
