* You can grow or shrink node selection by hovering the mouse pointer over a node and using mousewheel (up = grow, down = shrink) or the keys PageUp (grow) and PageDown (shrink). Growing adds the closest unselected node to the selection; shrinking deselects the farthest selected node. There are two modes that differ by how the closest/farthest nodes are chosen:
o Spatial selection (Mousewheel, PageUp/PageDown): distances to nodes are measured directly, regardless of which subpath a node belongs to.
o Linear selection (Ctrl+Mousewheel, Ctrl+PageUp/Ctrl+PageDown): node distances are measured along the path, and only the nodes belonging to the same subpath as the hovered node are considered (i.e. other subpaths are never selected).
This technique is convenient for quickly selecting an area in a complex path starting from a center - for example, for node sculpting.
Let me know if you think linear mode will be more often used than spatial - I can swap the shortcuts so that the more common mode can be used without Ctrl.
