Feature request: add an action (and keyboard shortcut) to move up one level in groups (exit current group)

I'm working on projects that have a quite deep groups tree; and I'm quite fed up double clicking to exit current group; especially when the group is large and I've to zoom out to find the group limits to double click out of the groupe to exit it.

I'd like to have an action (to be able to associate it a shortcut) to exit current group (move up one level).

Thanks a lot for this wonderful project !

EDIT: the solution is here
