On the Mac itself, I have remapped the caps lock key (does anybody actually use that thing these days?) to Command (that's the key with the weird symbol... ah well, one of the keys with weird symbols <g&gt . I had always done the same thing on Windows, where it required registry changes, so I was positively surprised to find that on the Mac it's just a system preferences option... Microsoft, here's how you do that kind of thing:

Now, while I've found it useful on the Mac to have the Command key easily accessible (although Ctrl is still used in too many places, like terminals and things... gotta find a solution to that), that key is recognized as a Windows key in VMWare. So I changed one of the registry trickery files so that the Windows keys get remapped to Ctrl for use in Windows. Works like a charm. Here's what the content of that .reg file looks like:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,1d,00,5B,E0,1d,00,5C,E0,00,00,00,00

Hope it helps somebody!
