How to set up keyboard mapping for OSX86 and Windows XP

1.In System Preference of Mac OS X, exchange Command and Control key

2.If you are using VMware Fusion like me
Open ~/Library/Preferences/VMware Fusion/config

Add following line:
mks.keyboard.swapAlt = TRUE

3.In you Win XP
Get KeyAssigner.exe from
http://ftp.isu.edu.tw/pub/Windows/softking/soft/tw/k/KeyAssigner.exe

Add mapping from CTRL to ALT and ALT to CTRL

It is done. Now you can use CTRL+V for paste and CTRL+C for copy on both Mac and XP.
