# Reference lookup > In-editor dictionary and thesaurus — press ⌘' (or use the command palette) to look up the word under your cursor without leaving the draft. Also known as dictionary, thesaurus, ⌘' ## In practice Reference lookup keeps dictionary and thesaurus work beside the draft: press Command-' (shown as ⌘') on the word under your cursor, or open the command palette and search for the lookup. The panel opens without forcing you into another app that breaks writing rhythm mid-scene or mid-paragraph. Results can include definitions, synonyms, antonyms, near-meanings, rhymes, and a frequency cue for how common an option is. Pick a replacement and it drops in with formatting intact in Plot and Canvas. That is the difference between a real in-editor tool and a copy-paste scavenger hunt across browser tabs. Any online enrichment of definitions or thesaurus results is clearly labeled and can be disabled in Settings. Your draft stays yours; turn enrichment off when a room policy or personal preference wants offline-only lookup behavior during drafting or notes.

Press ⌘' on the word under your cursor, or open the command palette and search for the lookup. The panel opens beside your draft so you stay on the page. ### What does the thesaurus show beyond synonyms? Antonyms, near-meanings, rhymes, and a frequency cue — so you can choose the word that fits the line, not merely a different one. ### Does looking a word up send my writing anywhere? Your draft stays yours. Online enrichment of definitions and thesaurus results is clearly labeled and can be switched off in Settings. ### Does reference lookup work in Canvas as well as Plot? Yes. The same in-editor lookup is available in both products so research binders and screenplays share one word-craft habit. ## Related terms - [AI skill](https://www.inkwell.software/glossary/ai-skill): A structured AI pass that reads your document and proposes edits or findings in place — dialogue polish, continuity flags, coverage — as reviewable markup you accept or reject. - [BYOK](https://www.inkwell.software/glossary/byok): Bring Your Own Key — connect your AI provider API key so chat, ghost-text completion, and skill passes run on your account, with usage you can see in that provider’s dashboard. - [Block editor](https://www.inkwell.software/glossary/block-editor): A document model built from typed blocks — paragraphs, headings, lists, embeds — instead of one undifferentiated page.
