<div class="markdown_content"><p>Und noch ein Tipp (für Einsteiger / Umsteiger):</p> <p>Man kan mit einem rechten Mausklick in den Deklarationsteil dessen Ansicht einen Tabellenmodus umschalten.</p> <p>Der hilft in jedem Fall bei den ersten Deklarationen, oder wenn man sich bei bestimmten Deklarationen einfach mal unsicher ist. Fortgeschrittene User arbeiten aber überwiegend in der textuellen Ansicht, die man natürlich wieder genauso einfach zurückstellen kann.</p></div>
