# UI Basics

Audulus's UI at a glance:

- many operations use right-click context menus (control click if you have one button)
- to create a new node, right-click on the background, choose a node category and node type
- to zoom use the mouse wheel or two fingers on your trackpad
- to pan, drag the background
- to select a node just click on it
- to select multiple nodes, hold shift while clicking
- to select all the nodes required to compute a node's output, command-click on the node
- to make a connection between nodes, drag from an output to an input
- to disconnect, drag from an input
- to get help on a node, hover the mouse over it for about a second
