scale several bones envelopes proportionally I am looking to proportionally scale down (for example) all bone envelopes in the hand of an armature .
However I cannot seem to use the Deform Distance:

nor the Scale tool to effect the envelope distance of the multi-select, proportionally.

Is there a way to do this without resorting to scripting (python)?
It appears the Alt-S and Ctrl-Alt-S work to scale multiple, proportionally.
