If you have a Windows computer: Go to control panel and find your regional and language settings. For XP: in the languages tab, check the boxes to install East Asian languages and complex scripts (right to left languages). then click the "details" button on the languages tab. click the "add" button and add the korean keyboard. For 7: in region and language, there is a tab thats called "keyboards and languages." go to it, and click the "change keyboards..." button. In the general tab, just add the korean keyboard(: I don't quite recall, but I believe the process for Vista is similar. If you have a Mac, go to system settings -> language and text -> international. click the tab for input sources/menu or keyboard menu (tab label depends on your version of mac osx) and check the keyboards you wish to be activated. when you're in a word processing program or on the internet, you can click the little flag at the top (US flag if your language is english) and change it to whatever keyboard you want to use. Hope this helps :]

You change the input language. I have a Mac, so if that's what you have, I can tell you how to do it, or you can google "language input <your computer>". Or you can use an online keyboard, which you can also google.
