Can we assume it is too late to use the undo keyboard command?
Did the layer go into another layer, as a sub-layer? Do you see a disclosure triangle to collapse the sub-layer down and drag back out as a layer?
Thanks for the replies.
I was working with a file that slowed my computer down and I noticed after a glitch on screen that one of my layers panels had disappeared. I found it within one of the other layers but right at the bottom of the list. I dragged it up which seemed a bit of a inefficient way of getting in to the top of the list so that I could drag it out into its original position.
Is there an easier way of doing this? - hope this makes it a bit clearer...
First make anew layer where you want this layer to be.
Select the content of the layer you want to move in the layers panel that will select everything on the layer. hit the command x keys to cut the content of the layer.
Now select the new layer you created and paste in front or back command f or command b if you have CS5 you will also be able to use paste in place command shift V.
I think this would be the fastest way
Thanks - that should do the trick!
