How to merge two unconnected edges into a single one There are several questions on merging connected edges and edge loops, but I can't find the simplest case where we just have two edges:

  

and want them to be merged like this:

  

I don't have a requirement on the location of the final edge, but I guess a comprehensive answer would encompass the different possibilities: merging at active edge or at mid-distance.

I know I can:


move a vertex onto the other using the snap option,
select the four vertices,
remove the two doubles.


But that's four operations. Can it be done more quickly?
Maybe this is a little faster ... hmmm
But you will have to turn on the addon called "F2"


Select the 2 edges.
Hit F, connects the 2 mesh and gives you 2 original edges.
Select the extra edge you didn't need. Hit X dissolve the edge.
