Editor Essentials

  • Monaco provides syntax highlighting for Oracle SQL, auto-indentation, bracket matching, and error underlining.
  • Use snippets and multi-caret editing (Alt+Click on Windows, Option+Click on macOS) to modify repeated clauses.
  • The minimap on the right helps you navigate large statements quickly; click it to jump to sections.

​
Templates & History

  • Click the history icon to insert any recently executed query into the current tab.

​
Organizing Scripts

  • Separate multiple statements with semicolons. Koala’s semicolon-scoped runner figures out which statement to run based on cursor position.
  • Add comments (-- inline or /* block */)—they’re ignored during execution and stored with history for context.

​
Formatting

  • Press Alt+F (Option+F on macOS) to format the current statement using Koala’s formatter.
  • Adjust formatting preferences (uppercase keywords, indentation style) under Settings → Editor.
