+%D \extras

+%D \subject{Control buttons}
+%D
+%D Animations are useless without any method to enable them, one way
+%D is to use \tex{goto} command (e.g. \type{\goto{...}[JS(Walk_Field{<NAME>})]})
+%D where you go to the next frame with each click. A different way to control
+%D the animation is the menu, which can be a row with buttons below the animation
+%D or a link above the graphic.
+%D
+%D The module provides for this the following values for the menu key:
+%D
+%D \startitemize[packed]
+%D \startitem no (usefull when you use the \tex{goto} command) \stopitem
+%D \startitem yes (places a row with buttons below the animation) \stopitem
+%D \startitem overlay (creates a button over the animation) \stopitem
+%D \stopitemize

+%D   {frame,startframe}
+%D
+%D The content for each frame can be set with two methods, the first is to
+%D enclose the code in brackets like you do in the overlay environment.
+%D
+%D \starttyping
+%D \startanimation
+%D   {FRAME 1}
+%D   {FRAME 2}
+%D \stopanimation
+%D \stoptyping
+%D
+%D The second method is the modern variant with start/stop-tags to enclose
+%D each frame, you can either you use \tex{frame} command which takes
+%D a argument, e.g.
+%D
+%D \starttyping
+%D \startanimation
+%D   \frame{FRAME 1}
+%D   \frame{FRAME 2}
+%D \stopanimation
+%D \stoptyping
+%D
+%D or you use the \type{frame} environment which delimits each frame
+%D by the start and stop tags.
+%D
+%D \starttyping
+%D \startanimation
+%D   \startframe FRAME 1 \stopframe
+%D   \startframe FRAME 2 \stopframe
+%D \stopanimation

+%D To use the module one has to create a new animation environment,
+%D to prevent the user from creating one first before he can use the module
+%D one environment would be always available. The name of this predefined
+%D environment is \tex{startenvironment}, to ensure it can be also by other
+%D modules when a non english interface is used it is ensured you can always
+%D use it with two commands \tex{startanimation} and \tex{stopanimation}.
