   Notes: If the Show Delays command is active, the handle will include a number indicating the delay associated with the connection. If Show Delays is not active, for paths located from TimeQuest Timing Analyzer reports, the handle appears only as a small rectangle with a plus icon (+) at one end. If the Chip Planner view displays many highlighted connections that are not of immediate interest to you, you can use the Clear Unselected Connections/Paths command to remove from view all but the selected connection or path.
