# Configure Snippet and Prompt Expansion Triggers

> Customize the prefix and trigger sequences SprintBrain watches for so snippet and prompt expansions fire exactly when you want — and never by accident.

A **trigger** is the character or sequence SprintBrain watches for in text fields. When you type the trigger prefix followed by a snippet shortcut and press Tab, SprintBrain replaces everything you typed with the full expanded text. Configure your triggers in **Settings > Triggers** so expansions fire exactly when you intend — and never by accident.

## Default triggers

SprintBrain ships with sensible defaults for every expansion mode:

| Feature               | Default prefix / sequence   | Example                              |
| --------------------- | --------------------------- | ------------------------------------ |
| Snippet expansion     | `/`                         | Type `/greet` then press Tab         |
| Prompt picker         | `"""` (three double-quotes) | Opens the prompt browser             |
| Selection suggestions | On by default               | Select text to see matching snippets |

The snippet shortcut prefix and the trigger sequences are configured separately, so you can mix and match to suit your workflow.

## Customizing the trigger

Open **Settings > Triggers** to change any of the following:

<AccordionGroup>
  <Accordion title="Shortcut prefix">
    The character(s) you type directly before a snippet shortcut for instant expansion (e.g. `/hello` expands immediately without opening the picker). Choose from `/`, `::`, or `;`. The change takes effect the moment you save — no extension restart needed.
  </Accordion>

  <Accordion title="Snippet trigger sequence">
    The sequence that opens the **snippet picker** overlay. Must be 1–5 non-whitespace, non-alphanumeric characters. The sequence must not conflict with your prompt trigger sequence.
  </Accordion>

  <Accordion title="Prompt trigger sequence">
    The sequence that opens the **prompt picker** overlay. Defaults to `"""`. Must be 1–5 non-whitespace, non-alphanumeric characters and must not conflict with your snippet trigger.
  </Accordion>

  <Accordion title="Activation key">
    The key that confirms your selection in the picker — defaults to **Tab** for both snippets and prompts. You can set separate activation keys for each if your target sites intercept Tab.
  </Accordion>
</AccordionGroup>

<Tip>
  Choose a trigger prefix that doesn't appear in your normal typing. If `/` fires too often while writing file paths or markdown, `;` is a popular alternative that almost never appears in prose.
</Tip>

## Selection-based suggestions

When you **select a word or phrase** inside any text field, SprintBrain shows a small floating menu of snippets whose name or content matches your selection. Click a suggestion to replace the selected text with the fully expanded snippet — dynamic fields are filled inline before insertion.

You can turn selection suggestions off in **Settings > Triggers** if you prefer not to see the floating menu.

## Prompt shortcuts

In addition to the prompt picker trigger, every prompt in your library can have its **own dedicated shortcut**. Set it in the prompt editor (for example `/coderev` for a code review prompt). Typing that shortcut + Tab expands the prompt directly into the active field without opening the picker first.

Prompt shortcuts follow the same prefix and activation key as snippet shortcuts — there's one consistent expansion pattern to learn.
