Select the language you want to translate to by clicking the second box and clicking a language in the list.
After you’ve chosen languages, just type or copy and paste a word or phrase into the text box in the Google Translate window and press “Enter” to translate it. Click the “More” link that appears below the translated text.
You can also translate a Web page by typing or copy and pasting its address into the box in the Google Translate gadget. iGoogle will open a new Web page with the translated Web page.
Click the “Maximize” icon located on the right side of the gadget’s title bar to expand it to fill your entire iGoogle page and see more options.
If you’d like to try a different translation gadget, you can click the “Add Gadgets” link at the top-right corner of the iGoogle Web page to access the gadget gallery. Type a phrase such as “translate” into the search box at the top-right corner of the page and press “Enter” to see other available translation gadgets.
You can install everything from differently-designed gadgets that use Google Translate to translate text to gadgets that use third-party translation services such as WordMonkey or Babylon.
Click a gadget you want to use on the search results page and click the “Add it Now” button on that gadget’s page to add it to your iGoogle page.
