Unset

DESCRIPTION

  "unset" behaves in two ways.

  If selection is not provided, unset changes the named global
  setting to a zero or off value.

  If a selection is provided, then "unset" undefines 
  object-specific or state-specific settings so that the global
  setting will be in effect.

USAGE

  unset name [,selection [,state ]]

PYMOL API
