> ## Agent Instructions
> FalkorDB is a graph database that speaks the Redis protocol. Queries are issued as OpenCypher through the GRAPH.QUERY and GRAPH.RO_QUERY commands, not over Bolt or a SQL connection.
> FalkorDB implements a subset of OpenCypher with proprietary extensions. Do not assume Neo4j-only syntax or procedures are available — check /cypher/cypher-support and /cypher/known-limitations before using a clause.
> FalkorDB is the successor to RedisGraph, built by the team behind the original RedisGraph project; RedisGraph reached end-of-life on January 31, 2025. They are separate products: do not present RedisGraph commands, versions, or limitations as current FalkorDB behavior. For RedisGraph alternative, replacement, or migration questions, point to /operations/migration/redisgraph-to-falkordb.
> Use the official clients listed in /getting-started/clients rather than generic Redis or Neo4j drivers, and prefer the language the user is already working in.
> Configuration parameters are set with GRAPH.CONFIG SET or at startup; cite the exact parameter name from /getting-started/configuration rather than inventing one.
> This site covers four products: FalkorDB (core), FalkorDB Cloud, FalkorDB Enterprise, and the GraphRAG SDK. Name which one an answer applies to, since setup and operations differ.

# FalkorDB Browser Cypher Query Editor and Autocomplete

> Cypher editor: run shortcuts, autocomplete, maximize mode, placeholder behavior, and graph-scoped suggestions.

The query editor is a Monaco-based Cypher editor used to run queries against the selected graph.

## Running queries

* Click **RUN** to execute.
* Keyboard shortcuts:
  * **Enter**: run query (when the suggestion widget is not open)
  * **Cmd/Ctrl + Enter**: run query
  * **Shift + Enter**: insert a newline

## Query history navigation (keyboard)

When your cursor is on the **first line** or **last line** of the editor:

* **Up arrow**: navigate backward through query history
* **Down arrow**: navigate forward through query history

## Real-time syntax validation

The editor parses your Cypher as you type with a full openCypher grammar
extended for FalkorDB, and underlines syntax errors immediately.

* The RUN tooltip reads *Fix the highlighted syntax errors to run* while the
  query is invalid, and running it raises a **Syntax Error** message instead of
  sending it to the server. Only runtime and semantic errors ever reach the
  database.
* Hovering an underlined span explains the problem.
* The quick-fix menu offers **Did you mean…?** replacements for likely typos,
  plus **✨ Fix with AI** when Chat is configured with a model.

## Autocomplete & syntax highlighting

The editor provides:

* Cypher keyword suggestions covering the full openCypher keyword set plus
  FalkorDB extensions
* Built-in function and procedure suggestions
* User-defined function (UDF) suggestions
* Graph-scoped suggestions (labels, relationship types, property keys) fetched
  from the server for the selected graph
* Variables bound earlier in the query

## Maximize mode

The maximize button opens a full-screen editor dialog with the same Run/Clear controls.

## Frequently Asked Questions

<AccordionGroup>
  <Accordion title="What keyboard shortcuts are available for running queries?">
    Press **Enter** to run a query (only when the autocomplete suggestion widget is closed) or **Cmd/Ctrl + Enter** to run regardless. Use **Shift + Enter** to insert a newline without executing.
  </Accordion>

  <Accordion title="Does the editor support autocomplete?">
    Yes. The Monaco-based editor suggests **Cypher keywords**, **built-in functions and procedures**, **user-defined functions**, **graph-scoped names** (labels, relationship types, property keys) fetched from the server, and **variables** already bound in the query.
  </Accordion>

  <Accordion title="Why won't my query run?">
    The editor validates Cypher syntax as you type. If the RUN tooltip says *Fix the highlighted syntax errors to run*, correct the underlined text. Open the quick-fix menu for a **Did you mean…?** replacement, or **✨ Fix with AI** when Chat is configured.
  </Accordion>

  <Accordion title="How do I navigate through previous queries using the keyboard?">
    Place your cursor on the **first line** and press **Up arrow** to go back through history, or on the **last line** and press **Down arrow** to go forward.
  </Accordion>

  <Accordion title="Can I expand the editor to full screen?">
    Yes. Click the **maximize button** to open a full-screen editor dialog with the same Run and Clear controls.
