SilverBullet provides context-aware autocomplete to help you write faster. Completions are triggered automatically or via keyboard shortcuts as you type.

Page link completion

Type [ to trigger page name completion. SilverBullet searches across all pages in your space and offers matching suggestions. Select one to insert a [[Link](` to trigger page name completion. SilverBullet searches across all pages in your space and offers matching suggestions. Select one to insert a [[Link) to that page. If no page with that name exists, a link is still created — navigating to it will create the page (these are tracked as [Aspiring Pages](Aspiring Pages)).

Tag completion

Type # to trigger tag completion. SilverBullet suggests existing tags from across your space. This helps maintain consistent tagging — no more typos creating duplicate tags.

Emoji completion

Type : followed by a keyword to search for emoji. For example, :rocket offers the rocket emoji. Press Enter to insert it.

Frontmatter key completion

Inside a Frontmatter block, SilverBullet suggests attribute keys that are already used elsewhere in your space. This helps keep your metadata schema consistent.

Slash commands

Type / at the beginning of a line (or after a space) to trigger [Slash Command](Slash Command) completion. Slash commands can insert templates, perform actions, or trigger custom behavior defined in [Space Lua](Space Lua).

Lua code completion

Inside space-lua fenced code blocks, SilverBullet provides code completion for:

Global functions and variables
API namespaces (editor., space., index., etc.)
Table fields and methods
Function signatures and one-line documentation when the API provides metadata; selecting a documented function reveals its complete source-backed API documentation in an adjacent information panel

Ctrl-click or Cmd-click a Lua-defined function to navigate to its definition.

Custom completions

You can extend the completion system by subscribing to the editor:complete event via [Space Lua](Space Lua). Your handler receives the current cursor context and can return additional completion items.
