Hi @camille.bobeau @PPPPEWORIGUH ,

I tested Selection Cycling once again on my side.

Yes, this is not a trivial task, I agree.

Here are the steps once again:

1/ Set 

- selectionpreview to 3

- selectioncycling to 1 or 2

- legacyctrlpick to 2

2/ Activate selection cycling with Ctrl+W shortcut if it is not activated.

3/ Hover with mouse over the overlapping objects until you see preselection highlighting of one of the overlapping objects and special icon near crosshairs

4/ Press Shift key and start to press Spacebar - you should see how the the next objects are highlighted one by one 

5/ When necessary object is highlighted, release Shift key and pick with mouse on this highlighted object

That is all for selecting outside editing command.

If you are inside editing command, continue:

6/ Right-click to accept selection or

7/ Continue to select other objects, then  Right-click to accept selection.

8/ Continue with editing command.
