How do I make ctrl-dragging (to snap to other paths) the default way of dragging in Adobe Illustrator cs6 -- without pressing any key? I recently upgraded from Illustrator cs3 to cs6, and I had this behaviour in cs3. And I'm missing it.

Answer: Here is a little something that you can use to find your cycles.

declare @T table
(
  ID int,
  Parent_ID int
)

insert into @T values
(1, 3),(2, 1),(3, 2),    -- This is a cycle
(4, 4),                  -- This is a cycle
(5, null),(6, 5),(7, 6)  -- This is not a cycle

;with C as
(
  select T.ID,
         T.Parent_ID,
         cast(',' + cast(ID as varchar(10)) + ',' as varchar(max)) as Path,
         0 Cycle
  from @T as T
  union all
  select T.ID,
         T.Parent_ID,
         C.Path + cast(T.ID as varchar(10)) + ',',
         case when C.Path like '%,'+cast(T.ID as varchar(10))+',%' 
           then 1 
           else 0 
         end
  from @T as T
    inner join C  
      on T.Parent_ID = C.ID
  where C.Cycle = 0
)
select *
from C
where Cycle = 1


Result:

ID          Parent_ID   Path       Cycle
