2 To lock just the nodes inside a group, while still allowing the group itself
to be moved, right-click on the title bar of the visual group node and
select Lock Tools.
To open or close a visual group node:
1 To open a group node, right-click on the node and select Open or press
Shift + O. Opening a group node displays the contents of the group
node while applying the visual group attribute.
2 To close a group node, right-click on the title bar of the group node and
select Close or press Shift + C. Closing a group node removes the
visual attributes of the node and collapses it back to its regular appearance.
To ungroup a group:
➤ Right-click the group node or the title bar of the visual group node and
select Ungroup, or press G.
To add input or output connections to a group node:
1 Enter the group node by double-clicking the node, then drag the link
from an input or output beyond the top border of the schematic. Control
will be transferred to the group level one up in the hierarchy. At this
point, releasing beyond the border will create a connection node. Moving
within the border will allow connection to another node. If this group
level is not the top most, moving within the border and back up again
will transfer control to the next group up in the hierarchy. Moving down
in the group hierarchy is accomplished by dragging beyond the bottom
border of the Schematic view. All dragging must be done in conjunction
with the Shift hotkey.
2 Enter the group node by double-clicking the node, then right-click and
select New Output Connection. Note that the cursor must be over an
input or output.
