Defines the timing of modifier key to reset the bar visibility.
To reset the visibility of the bar with the press of the modifier key use *press*.
Use *release* to reset the visibility upon the release of the modifier key and only if no other action happened while the key was pressed. This prevents hiding the bar when the modifier is used to switch a workspace, change binding mode or start a keybinding.
