Hello @ppc_world
Sorry, by list we mean the layout list.
In Bluewin the checkboxes are called check fields.
You can find the setting for this directly in the gear menu-> control fields
In a list, you can also hold down the Ctrl key and then use the left or right mouse button to mark or unmark individual elements. This works the same everywhere under Windows. But it’s easier with the checkboxes.
