First, you need to enable advanced menus (via prefs, Adv) if not already on.
Using Rotate as above as an ex.
Select geom
Choose Rotate with rmb (or mmb, note info line contents) - rmb for just defining a (rotation) axis, mmb if you want that axis to pass thro’ a specific location.
Select an edge (say) and execute op - selected geom will now rotate around this edge.
Similar procedure for all ops that support these options - more info about vector behaviour on the aardvarks’ vector page, if interested.
Note that all of this sort of stuff can be done using magnets as well - check info line for details, as options vary depending on camera mode being used - but for Mirai mode, you just hold Alt key.
Group - select objects, Object > Combine (use Separate to well, … separate
) - but note that wings doesn’t keep object names thro’ this procedure.
Far better off (imo) if you want to rotate a ‘group’ of objects:
Select objects but don’t group and do a rmb (mmb) rotate - this’ll keep names.
