 Rotating a node can be done in three ways:
+
 - Click near the center of a face, and the node rotates 90° around it.
 - Click near an edge, and the node will be rotated 90° away from you.
-- Clikc near a corner, and the node will rotate 120° around it.
+- Click near a corner, and the node will rotate 120° around it.
+
 Sneaking inverts the direction of the rotation.
 
 At this time, nodes that can be rotated are hardcoded into the mod, since

+A function mimicking NodeCore's `node_spin_filtered` has to be provided.
