Missing setting for Mac Mail on Moutain Lion

[Google Code Exporter]

In "secrets" I cannot find the setting to disable the send animation in Mac 
Mail on Mountain Lion. On Mountain Lion you can deactivate by executing this:
defaults write com.apple.mail DisableReplyAnimations -bool TRUE

Please can you add it to "secrets"?
