or also to background layers (in which case it creates copies of the lines /
rings and adds them to the edited layer).
It is thus ideally suited for the creation of distance line layers.

To create a shift of a line layer, you must first go into editing mode
To create a shift of a line or polygon layer, you must first go into editing mode
and activate the |offsetCurve| :sup:`Offset Curve` tool.
Then click on a feature to shift it.
Move the mouse and click where wanted or enter the desired distance in
the user input widget. Holding :kbd:`Ctrl` during the 2nd click will make an offset copy.
Your changes may then be saved with the |saveEdits|
:sup:`Save Layer Edits` tool.

For geometries on background layers make sure that snapping is on and hold :kbd:`Ctrl`
to select the geometry from the background. Also hold :kbd:`Ctrl` when doing the second click
or when pressing enter after entering the desired distance.

Are you sure you need to hold Ctrl when you press Enter? I can't confirm that one.

That's how it worked on my system (windows) otherwise it doesn't do anything because it does not copy it from the other layer.

I meant, for background layers, you have to:

  1. Snap and Ctrl+click to select the geometry to copy
  2. Move or enter the distance, and you should get a preview
  3. Ctrl+click to past the offset copy. Or press Enter. But I read here Ctrl+ Enter. Or do I misunderstand? Both work on macOS but I want to be sure we don't add unnecessary constraints.

I went back and tried it again and you are correct. When I was testing before I swear it wasn't working that way.
I'll remove the Ctrl+Enter. Thanks

Geometries will be converted to line or polygon depending on the layer types.
