In an attempt to enable Korean IME users, who happen to be dual booting Windows on a MacBook Pro or attempting to switch the IME to Hangul Input mode without a right Alt button on their keyboard... there is now HangulSwitcher.
Running this tiny app will allow you to substitute pressing the right Alt button for Ctrl+Space. Doing so will send the Hangul mode command to the Korean IME thereby toggling it. Useful for people in this situation who don't want to have to use the mouse to click Back and Forth.
To add to the usefulness of this application I've provide the source code in C# for anyone interested in how to write a simple tray icon application that registers a HotKey and sends input using Windows API's and not the built in .NET libraries.
