I need Windows for my development environment on my Mac. I use Alt-U and Alt-S a lot in this software. These keys don't work as I expect on my Mac. Is there a way to send the Alt key presses to the virtual machine? I have a Windows XP VM running. Alt-U shows the Accessibility Utility Manager. Pressing Alt-S just types an "s". At work on Windows XP, neither of these behaviors happen.
If you go into the Parallels preferences--> Keyboard, you can set up custom profiles for how you would like the key commands to act for the Mac and the PC. There are a lot of options, so I am sure you would be able to to get your desired affect. This may require using it in conjunction with Coherence to get it to do exactly what you are looking for.
Control to select broken Once I upgraded to Lion I can no longer use the control or shift key to make extended selections in Windows 7.
