Context menus: radial marking menu in the viewport (Repeat on top, Undo, Delete, Press Pull, Create Sketch, Extrude, Move/Copy, Hole; right press-and-hold or a right drag on the ring flicks to pick), contextual lists for faces, edges, bodies, sketch entities (construction, fix, applicable constraints) and empty space; browser menus for bodies, sketches and components; rename box, Properties window; body.rename and sketch.redefine commands; ui.menu / ui.menuPick / ui.rename control methods
