File and display buttons
The file buttons are for saving the working file and quitting the program. The display buttons allow the user to alter the display to make it easier to work on the token. When nodes
are collapsed, only the root of the collapsed subtree is visible. The user is urged to experiment with the available options to see their effects before beginning annotation work for
the first time.
Save Saves the file being viewed in its current state. Shrink Shrinks the token being viewed to make more of it visible. Disabled. Swell Undo a prior shrink operation. Disabled. Show Only Listed Nodes Displays only node labels on the "Show" list, as created with the "List" button. Show All Nodes Undoes a Show Only operation and displays all nodes.
