award Unfortunately that's not what I'm looking for. We can already do that in Godot 3. But In Godot 3 we can ALSO set anchor only
in just two mouse click, which is not possible to do in Godot 4.
Dragging the green gizmos is clunkier if we don't really need special position for the anchor. Editing the number one by one is also the same.

I'm not that interested in using key modifier to set anchor, I just want to assign anchor only
, without resizing or moving the node.
Well, if this feature is truly gone, then I guess I will wrote a proposal to return it.
UPDATE: It was removed.
