" I'm running Excel 2007 on Windows XP Pro (guest) on Mac Pro (host) with a Mac keyboard. On a PC (on excel), it is possible to select non-contiguous cells using the control key, but this appears not to work in my current configuration. I've tried control+, apple+, shift+, option+...." "I have tried key mapping disabling under Parallels Desktop -> Preferences -> Keyboard & Mouse tab -- I have unchecked all possible items from the list under Windows and Generic profiles and uncheck 'Enable Mac OS X system shortcuts' box but it is not better". I've tried every combinations... "Is there a solution for this? It's something I do frequently and would greatly appreciate any ideas."
