Code Editor

The Code Editor is the KCL source panel for the active model. It also opens project text files selected in the File Explorer.

What You Can Do

• Edit the model directly in KCL.
• Format code, copy code, and open KCL docs from the pane menu.
• Use diagnostics, lint markers, and syntax-aware editor behavior.
• Use undo and redo within the app's editing workflow.
• Edit UTF-8 project text files up to 1 MiB with automatic saving. Markdown files have syntax highlighting; other non-KCL text files use plain text editing.

What You Cannot Do

• Treat point-and-click edits as separate from code. In Zoo Design Studio, KCL remains the source of truth.
• Rely on clipboard features if browser permissions block clipboard access.

Key Differences in This Area

• KCL source is the model authority, so graphical edits and code edits stay linked.
