In LaunchBar I am used to pressing and holding the activation keyboard shortcut (Command-Space for me) in order to send the selection (file or text) to LaunchBar (ie, the Instant Send feature). Is there any way in Alfred to use this "press and hold" method for passing the selection to Alfred? I find that this is so ingrained in my keyboard habits, it makes it very hard to consider switching to Alfred. I would much rather use press-and-hold than have to remember a separate hotkey sequence just to select something.
