--when the dock is hidden or in animation no mouse
wheel actions are accepted
--laucher: only the up action is accepted in order to
activate that launcher
--window: up action shows the window, if it is shown
nothing happens,
down actions, minimizes the window, it is is already
minimized nothing happens
--group: up/down to cycle through the windows
