3ds Max 2012 Curve editor moving keys verticality only?

Cint128

Hey guys, im having some trouble animating in 3ds max. I want to move a bunch of keys upwards in the y value to make my object higher, however i dont want to move the keys horizontally in the curve editor. Similar to when you go to keys and click slide but verticality instead of horizontally. I thought this was what the drop down on the move keys was supposed to do but it doesn't change anything.

Anyone know a way I can achieve this or what Im doing wrong?

Thanks

hey if anybody else has this problem found out it works if you go to the classic mode by Right click on curve editor tool bar and go load layout, function, curve layout classic
