vopen

Open a file or URL in the vlx-term center pane (mirrors the vopen command). Markdown opens in a WYSIWYG editor, images in the built-in image viewer, other files in the source-code editor (with automatic syntax highlighting by language), and http/https URLs in a built-in browser tab. Only use when the user explicitly invokes /vopen or $vopen; never auto-trigger. Available only inside vlx-term-hosted local sessions.
