The abbreviated menu button to the right of Model: in
the command window can be used to load a new dynamical system
or reload the defaults of an old one. This button holds a
pullright menu where each of the entries Mapping Examples,
Vector Field Examples, and Special Dynamical Systems
contains a submenu which may be displayed by moving right while
continuing to hold the
button.
This can also be used to conveniently restore defaults for a
system. Follow the Vector Field Examples entry to the right while
holding
and select Lorenz System again. Now the values
of parameters and variable ranges for graphing are as they originally were.
