Hi,
I pined some parameters in channel list. I want key only these channels by press “K”.
But when I select other object, the auto scoped channels appended.
Is there any option can disable auto scoped globally ?

Yes, we have a preference for that at the very bottom of the Animation Preferences dialog.

It's in the section When Nodes are Selected:

• Scope parameters with AutoScope enabled.
  Scope parameters with Animation

  Worked thank you !
  
  I found a problem that Scope parameters with Animation has no effect if checked/no-checked.
