On my laptop the Unity Dash often launches really slowly. I might press the Windows button, and sometimes it will take up to 15 seconds to open, and the system becomes unresponsive during this time. This is especially likely if I haven't opened the launcher in a few hours.
I have Gnome-Do installed, and I currently launch it with "Ctrl + Space", and it launches instantly and is very responsive.
I would like to swap my shortcut keys, so Meta (the Windows key) launches Gnome Do, but I can't figure out where to change the keyboard shortcut for the dash. Any clues?
