Khmer Virtual Keyboard

I’ve come across Khmer keyboard where you can click and type in Khmer, then copy and paste the text wherever you want. I found it through http://cambodiahomesweethome.blogspot.com/. To use Khmer virtual keyboard go  to http://khmergo.net/vkeyboard/ (KhmerGO means Khmer language in Japanese, I think Khmer in Japan invented it). I pointed out two red arrows, the one at the upper left is where you type the text, the lower bottom with green button is ’shift’ key for sub-consonants.
I must tell you, it really makes life easier. I struggled for a long time figuring out Khmer alphabet on English keyboard. Still didn’t come out as I expected, some of the alphabet didn’t appear as it should be. It took me forever to write a few words but using Khmer virtual keyboard, it took me less than a minute to type the words below. It is SO NICE to be able to write in Khmer. Thanks to the creator for making it possible!

[Update]:
As far as Khmer font,
Only Windows Server 2008 and Windows Vista support Khmer font, if you don’t have one of these, you need to install Khmer font on your machine to able to read or write in Khmer language. There is a good link where you can download beautiful Khmer fonts. http://www.wazu.jp/gallery/Fonts_Khmer.html
