  4. The current position is marked with a small circle and its parameter value is indicated.
  5. Click to insert a knot, or click an existing knot to increase its multiplicity.
  6. This tool always runs in continue mode: optionally keep inserting knots and/or increasing multiplicity values.
  7. To finish, right-click or press Esc, or start geometry or constraint creation tool.
