Connecting Vertices Question.

-If I am in edit mode, and there are two objects with two separate vertices,
where I wish to have one point coincide with the other, and
have the two objects join, <<ctrl> + <j>>, instead
of using <<ctrl> + <c>> to copy the x,y,and x value,
is there a one hit key combination to have all 3 values from one equal the other?

Make one vert in the object you want to move-the origin in obj mode, then on obj mode use vertex snapping and snap one to the other!

Many thanks. That would be it!
