Install Khmer Unicode Keyboard on Mac OSX Lion v10.7

Installing Khmer Unicode Keyboard

Khmer font was added by default on Mac OSX Lion v10.7 but you have to enable it by go to
- System Preferences then Language & Text
- Under Input Sources tab, check Khmer from the "Select input sources to use." pane.

Or you can also download the keyboard layout and install it from Cambosastra website (read its instruction).  

Problems

1. The Khmer keyboard layout come within OSX maps 'F' key to letter 'ផ' instead of 'ថ' so you should use the layout from Cambosastra team instead by selecting 'Khmer V2' in Keyboard preferences.

2. In Microsoft Word, the Apple's Khmer font named "Khmer Sangam MN" is broken; It does not display correctly when you type. You should install another font such as Koh Santepheap. You can download it from here too.
