How to get CAA/EKL parameter name ?

Hi, everyone
I want to know the lathe tool's Setup Angel (in Edit local parameters) and tool axis angle (in define MO windows) CAA/EKL parameter name.
by default, When the mouse stays on this parameter, it will be automatically displayed.
and I will try the "What's This" command, but it not work.
Does anyone have any suggestions? Thank you !!
