Key Editor Articulation Pane KeyCommand

Could anybody tell me how to set up a Key Command to open and close the Articulations/Dynamics pane at the bottom in the Key Editor? I could not figure it out myself. I hope it is possible to set a specific key command which functions for both opening and closing respectively depending on whether the panel is already opened or not. I would also like to use this for the Velocity panel.


I’m afraid, this is not possible.
