 \section{Changing a Specific Symbol in an Existing Mapping}
 If you should want to change a specifig entry of a specific mapping it would
 be rather tedious to redefine the whole mapping.  That is why \chemgreek\
 provides a command for that purpose:
-\begin{beschreibung}
-  \Befehl{changechemgreeksymbol}{<mapping name>}\ma{upper|lower}\ma{<entry
-    name>}\ma{<entry>}\newline
-    Changes the \code{upper}- or \code{lower}case entry \code{<entry name>} in
-    the mapping \code{<mapping name>}.
-\end{beschreibung}
+\begin{commands}
+  \command{changechemgreeksymbol}[\marg{mapping
+    name}\Marg{upper|lower}\marg{entry name}\marg{entry}]
+    Changes the \code{upper}- or \code{lower}case entry \meta{entry name} in
+    the mapping \meta{mapping name}.
+\end{commands}
 
 In order to activate the change you need the (re-) activate the affected
 mapping afterwards:
-\begin{beispiel}
+\begin{example}
   \changechemgreeksymbol{default}{lower}{alpha}{xxx}
   \selectchemgreekmapping{default}
