OMG thanks it works perfectly.
can a variation of that work for my second text layer which does the reverse of that? not sure if it makes a difference that the ease is applied to the keyframes with [0, temp] as opposed to [0,0]?
Keyframe 1 will be [0,0]
ease into keyframe 2 [0, temp]
ease out of keyframe 3 [0, temp]
Keyframe 4 will be [0,0]
thanks
