Node

Opens the node type menu to let you add a new node to the current network.

File Node

Opens a file browser to let you choose a file, then creates a File node to import that file.

Network Box

Cut

Copies the selected item(s) to the clipboard and removes them from the network.

Copy

Copies the selected item(s) to the clipboard.

Paste

Pastes any items on the clipboard into the current network.

Delete

Rotates the order of the inputs into the selected node. This may be useful with a multi-input where the wires are crossing.

Scope Channels

Scope any animated parameters on the selected node(s).

Delete Channels

Delete any keyframe animation on the selected node(s).

Collapse Selected into Sub-Network

Moves the selected nodes inside a newly created subnet node.

Collapse Selected into Material

In a material network, takes the selected "loose" VOPs and creates a new Material VOP node with them inside.

This is very useful when you're bouncing between a few different networks constantly, for example a source geometry network, dynamics network, and render network.

Jump to Quickmark

The items in this menu allow you to recall a network location assigned to a quickmark.

Last View

Jumps to the previously viewed network location. Pressing this key repeatedly bounces you back and forth between the last two locations.
