Spacebar Quick Preview

MakerVault’s quick preview works like macOS Quick Look. Select a file and press Space to open a full-screen preview overlay.

How to use it

1. Click a file to select it.
2. Press Space to open the preview.
3. Press Space or Escape to close it.

What you see

The preview overlay shows:

• File preview — The file rendered natively (for supported types) or a placeholder icon
• Metadata sidebar — Filename, size, type, tags, notes, and embedded metadata
• Open button — “Open in [App]” to launch the file in its default application

Preview modes for LightBurn files

LightBurn files show a segmented toggle in the top-right of the preview overlay:

• Canvas — An interactive SVG canvas rendering the actual cut layers, shapes, and text from the file. Supports pan and zoom.
• PNG — The embedded thumbnail image baked into the file by LightBurn.
• Photo — Shown only when you have uploaded a custom photo for the file.

Opening full-screen preview preserves whichever mode was active in the right sidebar.

Custom photo

Any file can have a custom photo (JPEG or PNG) that you upload. Once uploaded, a Photo tab appears in the preview toggle. The photo also appears as the primary thumbnail in grid view.

Inline preview

Previewable files also show a smaller inline preview directly in the file detail panel on the right sidebar, so you can see a preview without going full-screen. Double-click the inline preview to open the full-screen overlay.

Supported types

See Supported Previews for the full list of what renders natively vs. what shows a placeholder.
