Cut edges in the UV Editor I have an UVMap and I try to editing that. As we can see below there are couple of faces which are not placed very well. 



So I would like to separate those faces in order to place them from here:



To here:  



But I can't find the solution to cut edges to separate faces in the UV Editor.
1: In the UV/image Editor select the vertices/faces thet need to be moved and use the Keyboard shortcut key Y to separate them. 

2: Move them to their new position. 

3 To join them back to the UV's...... select each pair of vertices to be joined then open the Weld/Align menu with the W key and choose Weld.
