C. Call up description

<p>While being in the working field just click the variable with the right mouse key and then on 'Description' in the context window. By calling up the selection list via the button VARIABLES it is always the first variable which is marked by the dotted curser frame. Instead of clicking the desired variable (which would change its selection) you just move that frame by going up and down with the curser.</p>

<p>By clicking on 'Description' the text appears next to the list - whether the variable stands on a red or the white field (selected or not).</p>
