AndroTranslate is a Chrome extention that corrects typos that appear because you forgot to switch your keyboard to another language. The resulting typos look like strange, jumbled anagrams. Koreans dub this type of weirdenss 'Andromeda', meaning something alien from outer space. I often forget to switch my keyboard from and to English.
Install this extension, and you will see a context menu appear every time you right click on highlighted text. Select the context menu, and your typo will be replaced with the corresponding converted text. Screenshots with detailed instructions on how to use are posted with the Chrome web store page.
This is especially useful when I do a fresh install of Ubuntu and my Korean keyboard is not set up. The extension only supports English to Korean conversions at the moment.
