The Network Editor is a pane type in TouchDesigner that is used to create and modify Operators. The Network Editor is the default pane type for TouchDesigner and is visible when the program is launched. Navigating in the Network Editor is an important skill to learn early in TouchDesigner. Mastery of the Network Editor allows you to more easily modify and update your networks over time. The primary tool for network navigation is the mouse, although some operations have menu or keyboard equivalents. Each mouse button manipulates the Network Editor interface in a different way.
Use the left mouse button (LMB) to select nodes. Select multiple nodes by holding down the LMB and highlighting all desired nodes. Alternatively, you can hold down the Ctrl key and left-click on each individual node you want to select. To move a node, select it and keep the LMB depressed to drag it around the Network Editor. Release the button to place the node.
The middle mouse button (MMB) controls the zoom level. The current zoom level is always visible at the top left corner of the Network Editor. When you first start TouchDesigner, the initial network defaults to a zoom level of 5. To return to Unity Zoom (zoom level of 1), use the keyboard combination "Shift+h".
Click and hold the MMB to activate the Network Editor's zoom capabilities. While holding down the MMB, move up or right to zoom in, or move down or left to zoom out. If the middle mouse button is also a scroll wheel, scroll forwards to zoom in and scroll backwards to zoom out.
You can also box zoom by holding down the Ctrl button. To zoom in, hold down Ctrl and draw a box from left to right with the MMB. To zoom out, draw the box from right to left.
The right mouse button (RMB) navigates networks without changing the zoom level. Click and hold the RMB in any node free area and move the mouse around to move around the Network Editor in similar fashion. A scale representation of the visible part of the Network can be toggled on and off with the "o" key.
