Workspace and editing

Basic node operations

1. Select a node.
2. Choose Edit, double-click where supported, or use the edit shortcut.
3. Press Enter to confirm; use Esc to cancel where supported.
4. Add a child, sibling, parent, or child layer from Node Manager or the context menu.
5. Use Copy, Paste, or Paste Text to reuse structure or plain clipboard text.

Deleting a node with content may ask for confirmation. Read the dialog carefully: depending on the operation, children may be moved to the parent or removed with the branch.

Notes and rich content

Choose Add Note or Edit Note on a selected node. Notes can be plain text, Markdown, or HTML. Markdown notes support formatting, code blocks, LaTeX display math, and Mermaid fenced blocks:

```mermaid
graph TD
    A[Start] --> B[Finish]
```

Use View → Show Notes to show or hide notes across the canvas. A note icon opens one node's note.

Images, formulas, markers, and stickers

• Insert Image attaches an image to a selected node.
• Insert LaTeX adds a rendered formula.
• Markers communicate status, category, sequence, progress, flags, stars, and questions.
• Stickers add SVG illustrations and preserve their aspect ratio when resized.

Links and connections

• Web links accept https://, mailto:, sms:, and tel: URLs.
• Page links jump from a node on one page to a node on another page.
• Custom connections link any two nodes. Select the source and target as prompted, then complete the link.
• If a link target was deleted, recreate the link after confirming the target exists.

Outline and summary

Select a group of nodes and use Outline to create a visual boundary, or Summary to add a summary node. These objects help explain a group without replacing the underlying tree.

Read-only mode

Read-Only Mode prevents editing and is useful for review or presentation. Turn it off before using editing or AI actions that require write access.
