Object › Lock › All Artwork Above and Object › Hide › All Artwork Above
lock or hide the objects that are above the selection in its layer and
overlap it. Such an object can be a group or a sublayer that holds
another selected object. The commands left that object selected, the
key object included. Align then moved the locked object, or aligned
the other selected objects to the hidden key object. object.lock and
object.hide clear the selection, and layer.setProps, which the Layers
panel's eye and lock columns run, deselects what it hides or locks.
Both commands now deselect every selected object that is locked or
hidden after the command, as layer.setProps does, and clear the key
object when it is one of them. Undo selects the objects again and
restores the key object.
