Keyboard shortcut not working in yosemite Here is the screen shot and it's not working anymore after upgrading to Yosemite


NOTE: Although if I add this shortcuts under all applications then it works.
I don't know why it's not working, wasted my time and I found on apple discussion forum that in Languages there should be only one language and that doesn't work for me.
I have reported this bug to apple and it's still not being closed. I will update my answer once it's closed.

Till then you can add this shortcuts under all applications(instead of preview) then it will work.
