looking for the opposite of the accordion move


I can’t find a hint in the manual.
Staff spacing: With alt-drag I can squeeze the staves which are positioned in the direction of the »accordion« drag. Ok.
But is there an opposite command too? Means: How can I enlarge the space of staves by »accordion« dragging? (In order to close a too large gap between two staves without trying around by typing in a lot of mm-data?


IIRC Not yet.

Thx, Derrek!
