Insert at point (mouse copy/yank)

[Harry Putnam]

I've been digging thru C-h b for this command but I guess it doesn't
have a binding.

I used to have something in .emacs that caused a yanked piece of text
from a mouse copy in other documents to be inserted at emacs point
rather than where ever the pointer happens to be.  

That is, mouse scrape something in a different source, then hovering
mouse over document in emacs buffer and pressing mouse 2 to insert it.
Currently it gets inserted where ever the mouse is hovering.
I want it to insert at the emacs cursor.

Found this with M-x apropos <mouse.*yank><RET>
I'm not sure if this is related because it is set to t

  mouse-yank-at-point's value is t
  *If non-nil, mouse yank commands yank at point instead of at click.
  You can customize this variable.
  Defined in `mouse'.
