There are five components of the Material Graph window: Menu bar, Ribbon, Materials & Textures Library, Material Properties, and the Work Area.
1. Material Graph Menu Bar
New This will replace the working material and any textures with a basic diffuse material to start from scratch.
Save to Library will save the working material to the specified folder in your KeyShot Library.
Export This will allow you to export your material as a KeyShot MTL file type in a specified folder.
This provides quick addition of nodes to the Work Area.
Align nodes This automatically arranges connected nodes in the Work Area.
Zoom With complex materials the Work Area can quickly get crowded - the zoom options allow you to quickly adapt the Work Area to your current material.
Preview Options for previewing individual node settings such as color, alpha, and bump in the Real-Time. You can also stop the preview within this menu as well.
This gives access to hide/show the Material Properties window (4), Materials & Textures Library (5), and the Material Graph Ribbon (2).
2. Material Graph Ribbon
Save to Library - saves the current material to your Material Library
Add material node - adds an “Advanced Material” node*
Add Texture node - adds a traditional texture map and opens the file browser window to select your image file*
Add Animation node - adds a Color Fade node*
Add Utility node - adds a Bump Add node*
*Adds the default node of the category - you can easily switch the node to another type of the same category in the Material Properties window.

Align nodes - align the nodes within the Work Area
Zoom to fit - fit all the nodes within the Work Area
Zoom to 100% - view the nodes at 100% zoom level
Create Multi-Material - will convert the current material to/from Multi-Material
Refresh Geometry nodes - The geometry shaders (displacement, bubbles and flakes) need to be refreshed before any edits will be visible in the Real-Time View.
3. Material Graph Work Area
The Work Area displays all nodes their connections in a graph view.
In the work are you have following options:

Move the Work Area - Click and drag the work area to move it around.
4. Material Graph Properties
The Material Properties dialog shows the associated properties for the current node being edited - similar to the Material tab in the Project window but with the option to change node type.
5. Material Graph Libraries
The Materials and Textures Library contains an organized thumbnail display of all the nodes available.
