Mirror does the trick, but then everything is, well, mirrored.

You can also use "Change Layer" on groups. Select a group, then  
choose the change tool (the wrench), select "Layer..." and choose the  
layer you want your traces to be changed to. Then do a ctrl-right- 
click (cmd-right-click on Mac).
To swap two layers, say layer 1 with layer 2 you'd need three steps:
1. change the traces on layer 1 to layer 3 (turn off display other  
layers first)
2. change the traces on layer 2 to layer 1
3. change the traces on layer 3 to layer 2.

Was this what you were looking for?
