# Working with Canvas

## Basics of Canvas

**Add and Edit Nodes**

Select a node on a toolbar and click on it; the node will be added to the flow and automatically connect to the selected node on canvas.

Click the right mouse button to open the context menu, where you can:

* rename the node
* duplicate
* disconnect the node from the previous one in the flow
* delete

#### **Connect Nodes**

If no nodes were previously selected on the canvas and a new node was added, you will see a blue frame around the canvas and sign "Select input node." You need to select a node to connect to and click on it; a new node will be connected to the selected one.

You can disconnect the node via the context menu.

You can select multiple nodes, see [instructions](/data-flows/designing-flows/flow-designer-guide/working-with-canvas.md#multi-nodes-selection), and then:

* drag-and-drop selected nodes on the canvas
* delete all selected nodes via the context menu
* group nodes, see [instruction](/data-flows/designing-flows/flow-designer-guide/using-groups.md)
* add the union transform to merge selected datasets

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.tabula.io/data-flows/designing-flows/flow-designer-guide/working-with-canvas.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
