It seems that the command key remapping has been changed to include the CMD-S option. Any other changes there? I took a look a the Keyboard preferences option to see if it were possible to turn that feature off, but didn't find anything. I really would prefer that be turned off or allow us to specify any key that could trigger the remapping. I need to use Control-F to invoke a find command and I'd like to add that - or just turn the whole thing off and use Trade-keys, which I've been using on any Windows machine that I have to use. Anyway thanks for adding the S, now my documents aren't scattered with random s characters where I've attempted to save!
