The prompt reads "Select entity [RIGHT button ends]:". Use the crosshairs to select a point on an entity you wish to edit. (To select entities that are very close together, zoom in to get a more detailed view). CC3 searches the drawing for all entities that cross or are included in the cursor pick box. CC3 marks the entities found by drawing over them in gray. The prompt still reads "Select entity [RIGHT button ends]:". Continue selecting entities or right-click to move on to the next step.
Special cases: Pick text entities on their baseline. Pick entities with line width on their center lines. Pick smooth polygons and splines on their frames if showing, or on the curves themselves if frames are hidden.
