In Unified Modeling Language (UML) sequence diagrams,
you can remove interaction operands from combined fragments that
contain multiple interaction operands. Otherwise, you must delete
entire combined fragments to remove interaction operands.
You must have a sequence diagram with lifelines
and combined fragments open in the diagram editor.
To remove an interaction operand from a combined fragment,
in the diagram editor, right-click an interaction operand; then
click .
The interaction operand is removed from the combined fragment,
and all messages and interaction fragments that the interaction
operand contains are also deleted.
