Editor Basics

The Canvas

The workflow editor is a full-screen canvas powered by a node-and-edge graph. Every workflow is a directed acyclic graph (DAG): nodes represent individual operations, and edges define the order they execute in.

• Pan — click and drag on empty space, or hold the middle mouse button.
• Zoom — scroll up/down, or use the zoom controls in the bottom-left corner.
• Fit to view — click the fit button or press the keyboard shortcut to center all nodes on screen.
• Mini-map — a small overview in the bottom-right corner shows your current viewport relative to the full graph.

Node Library

The node library is where you find every available operation. Open it by clicking the + button in the toolbar or by pressing the spacebar.

Connecting Nodes

Connections (edges) define execution order. To create a connection, hover over the output handle at the bottom of a node until it highlights, then click and drag to the input handle at the top of the target node. Release the mouse to complete the connection.

To delete a connection, click on the edge line to select it, then press Delete. You can also right-click the edge for a context menu.

Node Configuration Panel

Click any node on the canvas to open its configuration panel on the right. The panel content depends on the node type:

• Connection picker — for action nodes, select which OAuth connection to use.
• Tool selector — pick the specific operation (e.g., 'list messages' vs 'send email').
• Parameter fields — input fields for the operation's parameters.
• Data picker — reference outputs from previous nodes using the {{ }} button.
• AI Suggest — let the AI pre-fill configuration based on your workflow context.
• Test button — execute just this node in isolation to verify the configuration.

Keyboard Shortcuts

A91I supports a full set of keyboard shortcuts for efficient editing. All shortcuts work when the canvas is focused.

Selecting Nodes

Click a node to select it. Hold Shift and click to add more nodes to the selection. Or draw a selection rectangle by clicking and dragging on empty canvas space — every node inside the rectangle is selected.

Press Ctrl+A to select all nodes. Press Escape to deselect everything.

Copy & Paste

Select one or more nodes and press Ctrl+C to copy. Press Ctrl+V to paste. Pasted nodes get new unique IDs and appear slightly offset from the originals so you can tell them apart.

Duplicate (Ctrl+D) is a shortcut for copy-then-paste in a single step. It creates an identical copy of the selected nodes immediately.

Node Groups

Groups let you organize related nodes visually. Select two or more nodes and press Ctrl+G to create a group. A colored container wraps the selected nodes.

• Label — double-click the group header to rename it.
• Color — right-click the group to change its color.
• Collapse — click the collapse icon to hide the group's contents and reduce visual clutter.
• Ungroup — select the group and press Delete to remove the group wrapper without deleting the nodes inside.

Undo & Redo

A91I maintains a history of up to 50 recent changes. Every action that modifies the workflow — adding a node, deleting an edge, changing a parameter, moving a node — is recorded in the history stack.

Press Ctrl+Z to undo. Press Ctrl+Shift+Z or Ctrl+Y to redo. The history is per-session and resets when you leave the editor.

Saving Your Work

Press Ctrl+S or click the save icon to persist your workflow. A91I saves the complete graph state — nodes, edges, positions, configurations, and trigger settings.

Next Steps

Now that you know your way around the editor, dive into the node types reference to understand every operation available, or learn how data mapping lets you pipe output from one node into the next.
