Where is the "copy/move to layer X" function, please?

I seek a function to duplicate entities from a layer to an other one.
Because when I past an entity to an other layer, this entity is past on the layer where it was created and not on the active layer.
Thks for your answer in advance.

I work on IntelliCAD version 10.0.1572.123806.PE.VC15.x64.CMS100a.
