# The Node Editor
## Node editor
The node editor is used to create and edit flows. The space bar can be used to bring up the **node palette**, which lets you search through all available nodes (functions and events), and place them on the canvas.
Nodes can be connected together by clicking on one of their properties, which starts the creation of a new arrow.
## Nodes
Function instances that have input or output triggers also get a play-button in their header, which can be clicked to execute a flow starting from that node.
