# Properties Source: concepts/properties.md URL: /concepts/properties # Properties Properties are frontmatter fields that Tolaria can display, filter, and edit. ## Suggested Properties Suggested properties are the fields Tolaria knows how to create quickly from the Properties panel. When a suggested property is missing, the panel shows a shortcut to add it with the right editor. | Field | Purpose | | --- | --- | | `type` | Groups the note into a type such as Project, Person, or Topic. | | `status` | Tracks lifecycle state such as Active, Done, or Blocked. | | `url` | Stores a canonical external link. | | `date` | Represents a single date. | ## System Properties Fields that start with `_` are system properties. They remain in plain text but are hidden from normal property editing. Examples include `_icon`, `_color`, `_order`, `_sidebar_label`, `_width`, and `_pinned_properties` on type documents or notes. ## Property Editing The Properties panel is the safest place to edit structured properties. Toggle it with `Cmd+Shift+I` on macOS or `Ctrl+Shift+I` on Windows and Linux. Date fields use Tolaria's picker, relationship fields can use wikilinks, and raw Markdown mode is available when you need direct control over YAML.
