You can change a node’s title (displayed at the top of the node) by double-clicking or hovering over the title and pressing ↵, then entering the new title in the node title editor that pops up. You may save or dismiss your changes by pressing ↵ or ⎋, respectively, just as you would using a port’s input editor. You can also select one or more nodes from your canvas and press ↵ to edit the node titles for each of the selected nodes in sequence. If you delete the title and don’t enter a new title, the node will default to its original title.
You can change a node’s tint color by right-clicking on the node, selecting
from its context menu, and selecting your color of choice. Tint colors can be a useful tool in organizing your composition. For example, they can be used to visually associate nodes working together to perform a particular task.
