What took place to "Roll up" alternative in Preferences/Window/Title bar Action?

I such as significantly the alternative "Roll up" in Preferences/Window/Title bar Action yet it is not there any longer in 10.10.

There are a means to get it back?

open the gconf-editor and also most likely to apps/metacity/general/action_right_click_titlebar and also transform it to toggle_shade
