Highlight text and get result from Google Translate in tooltip


This script works everywhere you can select text: Trados Studio, MS Office, webpages, PDF files... you name it.

When you first run the script, you can set your source language (either auto if you want Google to recognize the language or a two letter language code) and target language. There are some predefined languages I used most, but one can directly write in the edit boxes. Alternatively, you can modify the code and add the languages you use most. Adding a double pipe character "||" after a language makes it the one selected by default. You can call up the language selection interface by pressing [Ctrl]+[F12].

Just select the text you want to have translate by Google Translate (maybe not an entire page, since it will be not too readable) and press [F12]. Ah tool tip shows Google is busy translating and then you get the translation in a tooltip next to the caret position:


To make the tooltip with the translation disappear, just press [F12] again.


Text in green are comments in the code for better understanding. The code can be pasted like this in an editor.

If you have suggestions or ideas on how to improve this script, please don't hesitate to let me know!

Edit 1:

  • Small adaptation to make script work in Windows 10

Edit 2:

  • Simplification of code to avoid endless loops
  • Replacement of spaces in source tags by "%20" because literal spaces in the IE address bar lead to the error encountered by Paul
  • Option to save translation to clipboard
  • Option to close tooltip with translation on mouseclick
