By the way, you can also translate pages *to* Khmer. This is a little bit hackish (note to self: improve this!), and you can only do it for languages other than the language you use for the Chrome user interface (i.e. if you use Chrome in English, you cannot translate English pages, because Chrome assumes you can read English)
For example:
2) Chrome will offer you to translate it. Click Translate and it will be translated to English
3) Now change the language in the pull down menu from English to Khmer - and the website will be translated to Khmer
