Can mouse activation of plasma panels be turned off so that they show only on keyboard activation?

Hi, is it possible to set plasma panels to be hidden and only display on a keyboard shortcut? I like having them hidden, but I am frustrated by the mouse activation, which always activates when I am trying to do something else near the edge.

Not at the moment, no.

Ok thanks. Are there any launchers or dashboards that I can add a system-tray to?
