Snippets allow you to define custom [[Slash Commands]] that expand snippet style templates inline.

# Definition
You define a snippet by creating a [[Templates|template]] with a `hooks.snippet` attribute that configures the snippet. The following configuration options are supported:

* `slashCommand`: expose the snippet via the `/my-snippet` notation.
* `command`: expose the snippet as a [[Commands|command]].
* `key`: Bind the snippet to a keyboard shortcut (note: this requires to _also_ specify the `command` configuration).
* `mac`: Bind the snippet to a Mac-specific keyboard shortcut.
* `matchRegex` (advanced use only): match the current line against a regular expression, and replace the match with the template’s body.
* `insertAt`: by default a snippet is inserted at the cursor position, but alternatively it can be inserted at: `line-start`, `line-end`, `page-start` or `page-end`.

Minimal example:

    ---
    tags: template
    hooks.snippet:
      slashCommand: meeting-notes
    ---
    ## Meeting notes for {{today}}!

    |^|

## Frontmatter
A template’s [[Frontmatter]] is interpreted by SilverBullet’s [[Templates|template]] engine and removed when instantiated. However, to inject frontmatter after instantiation, you can use the `frontmatter` attribute.

Example:

    ---
    tags: template
    hooks.snippet.slashCommand: meeting-notes
    frontmatter: |
       date: {{today}}
    ---
    ## Meeting notes for {{today}}!

    |^|

Which will expand into e.g.

    ---
    date: 2023-11-11
    ---
    ## Meeting notes for 2023-11-11

    .

When the page already contained frontmatter before inserting the snippet, it will be augmented with the additional frontmatter specified by the template.

# Use
A snippet can be _triggered_ via the specified `slashCommand` via `/slashCommand` or via {[Open Command Palette]} and/or its associate key bindings when `command`, `key`/`mac` are specified.
