[orca-list] adding start up item on gnome tweak tool using orca 3.14.2

[Amir <trend669953 gmail com>]

Hi,
using gnome tweak tool on gnome 3.12.2, i want to add a new item to the 
start up  item of my ubuntu macine. But, when i've selected the "start 
up" category, i pressed ctrl+tab to move to the options, but i only 
found "button" on that. tab again, still "button." and after that, when 
i tab, orca says, "button menu." this button menu is for filtering, i 
think. So, there are two buttons on start up options in gnome tweak tol, 
but presses enter on both of them does nothing. so, what to do? routing 
te mouse and click it also does nothing. Is there any way i can ad start 
up items on ubuntu gnome with orca?
thanks
