Check that the mouse is over the node editor and the Shortcut switch is on. If it clashes with the Windows window menu, change the key under Keymap.

Linked trees (from a library) and library override trees cannot be tidied. Texture and Line Style trees are not supported either.

In our measurement (Windows, Blender 5.2) a 617-node tree took about 8 to 11 seconds. Trees with more than 250 nodes skip crossing reduction, so lowering Crossing trials does not make them faster. In scenes with heavy meshes, maximizing the node editor with Ctrl+Space may make it faster.

Tidying rebuilds manual reroutes (reroutes on a muted boundary that decide a value are kept). Ctrl+Z undoes it.

Blender 4.2 LTS – 5.2 LTS (Windows). macOS and Linux are not tested.
