I too prefer the new behavior. However, what is needed is an easy way to escape, via the keyboard, from the remote screen to the local.

I have found that Launchbar's double-tap (of the command key) to start a search does bring local Launchbar forward and thus activates local keyboard control. It doesn't seem to work every time and I'm not sure why it works, since command-space strictly goes to the remote screen, but it has been a partial workaround for me.

I was wondering if there was a keystroke for escaping to the local system. I do like the new behavior, but the only way I know to return keyboard focus to the local system is to find a bit of local desktop to click upon, which runs counter to my wish to have a full-screen Screen Sharing window. Are there any other ways to do this?
