*mode* dock|hide|invisible
Specifies the visibility of the bar. In _dock_ mode, it is permanently
visible at one edge of the screen. In _hide_ mode, it is hidden unless the
modifier key is pressed, though this behaviour depends on the hidden state.
In _invisible_ mode, it is permanently hidden. Default is _dock_.
*hidden\_state* hide|show
Specifies the behaviour of the bar when it is in _hide_ mode. When the
hidden state is _hide_, then it is normally hidden, and only unhidden by
pressing the modifier key or in case of urgency hints. When the hidden
state is _show_, then it is permanently visible, drawn on top of the
currently visible workspace. Default is _hide_.
*modifier* <Modifier>|none
Specifies the modifier key that shows a hidden bar. Default is _Mod4_.
