 ## Translation
 
-Search for **Conjure Translate**, identified by its centered 🌏 icon, and open it. Enter English in the search bar, choose a provider in the launcher header, then press Return or click **Translate**. Typing alone never sends text. Copy selected Japanese output with Command-C; the copy hint appears beside the Translate action at the bottom. The Back chevron beside the input returns to the launcher and restores your search; Escape dismisses Conjure.
+Search for **Conjure Translate**, identified by its centered 🌏 icon, and open it. Enter English in the search bar, choose a provider in the launcher header, then press Return or click **Translate**. Typing alone never sends text. When the translation is available, the action changes to **Copy**: press Return or click it to copy the full translation and close Conjure. Command-C still copies selected output. Editing the input restores **Translate**. The Back chevron beside the input returns to the launcher and restores your search; Escape dismisses Conjure.
 
 Editing the input, switching providers, saving or forgetting the key in Settings, or leaving Translate cancels the active request; cancelled results are not shown. After a request fails, submit again to retry.
