There is an app that resides in the tray called "fbxkb"http://linux.softpedia.com/get/Desktop-Environment/Tools/fbxkb-1868.shtml
As you can see in the screenshot, just click until you see the flag you need and you're using that layout you need. However, there is a cli command that you need to enter before you run the app. I have a link to that command on my other box. Give me a day or two to post the link. You may have to pm me in case I lose track of where I found this post.
Here is the link. Follow the instructions and then run fbxkb.http://tinycorelinux.com/forum/index.php?topic=1865.0
