Moving tokens between layers?

Hi, I'm new to Roll20 & loving it. How do you move tokens between the different layers?  I was setting up my 1st dungeon & wanted to use some tokens as backgrounds.  I got about half way through scattering dead body tokens around when I realized I was still operating on the Token layer.  I had to delete all the tokens I'd already put out & start over. I saw previous forum posts about issues with moving tokens between layers when the functionality came out, but I couldn't find any actual instructions on how to do it.  & the token right click menu didn't seem to have an option for it. Thanks

From  the wiki : Moving Objects Between Layers By default, when you create an object (such as by dragging and dropping a token image or a map onto the tabletop), it's placed on whatever the currently active layer is. Sometimes you may want to move objects between layers, though. To do so, you can right-click on the object, and from the Layers option in the menu that appears, select the new layer to which you would like to move the object. You can also use the keyboard shortcuts: CTRL+SHFT+O (CMD+SHIFT+O on Mac): Switch to the Objects/Tokens layer AND move any selected objects to that layer CTRL+SHFT+K (CMD+SHIFT+K on Mac): Switch to the GM Info layer AND move any selected objects to that layer CTRL+SHFT+M (CMD+SHIFT+M on Mac): Switch to the Maps layer AND move any selected objects to that layer A common use case of this is to move tokens from the GM Info layer (where they are not visible to players) to the Objects layer (where they are) when you want to "reveal" enemies to the players in a suprise attack.

Thanks, that's exactly what I needed.  The keyboard shortcuts to directly switch & copy between layers will be a big help too. Also I'd forgotten about the GM Info layer.  I put my surprises were in the empty spaces between the rooms. Thanks a lot
