Translate Selected Text Anywhere You Work on Mac
Highlight text in Safari, Chrome, Xcode, or preview documents and double-tap ⌘C. A lightweight floating HUD appears instantly next to your cursor with zero context switching.
How ⌘C+C Selection Translation Works
Traditional translation tools force you to copy text, switch to another window, paste, wait, and switch back. iTrans short-circuits this friction entirely.
Simply highlight any phrase, paragraph, or code snippet in any supported Mac application, and tap Command+C twice in quick succession. A floating native HUD immediately displays the translation, allows one-key copy, audio speech synthesis, and engine toggling.
