A group is a light-weight [[sub-system]], which is used only to group or package [[block|blocks]] graphically.

  * Groups are represented containers in the [[model screen#interaction matrix]] and [[model screen#graph]], and can be expanded or collapsed by pressing the + symbol.
  * A group will _not_ affect the [[ID]] of a [[block]].
  * Groups cannot be connected using [[connector|connectors]].
