Media Key Events in AppleScript?

Question

macOS

I want to optimize the volume control in Mavericks a little, therefore the question raised in the topic arose. The information on how to request the current volume level using AppleScript will also help.
Thank you in advance.

Answer 1

(*
volume 7 == 100%
*)
Terminal.app
osascript -e "set volume 7"
osascript -e "get (output volume of (get volume settings))"
AppleScript Edittor.app
get (output volume of (get volume settings ) ))
set volume 7
Set the volume from 1 to 7, get the value as a percentage.
