There are two functions for translating test from Internet or from Microsoft word. This is a screen scoot from the one used for large texts. You can copy single characters or large parts of texts and paste them into this page. On the page you can click on the characters to have them translated and read aloud by a Chinese voice. You can also ask the voice to read all of the text for you, with or without simultaneous translations.
If you are reading internet pages you can use this smaller window instead. It stays on top of your page all the time and is always ready to translate. As soon as you copy a character or text to the clipboard, it will paste it and translate it for you.
