A typical board design could include 8 signal layers, 4 plane layers and 10 mechanical layers, as well as the top and bottom silkscreen and ancillary layers, such as solder and paste masks. Layer sets are an ideal way of managing the display of this large number of layers.

PCB layer sets can be defined in the Layer Sets Manager dialog (Design » Manager Layer Sets menu). Any number of layer sets can be defined, and each can include any of the layers available in the board design.

To toggle the workspace to display a different set of layers, use the Layer Set control at the bottom left of the workspace. The popup menu will automatically present your current list of Layer Sets. Include the & character in the Layer Set Name to define the following character as an accelerator key.
