Typewriter effect right to left word per word

This is an old thread, but this is the solution:

Add a text animator for position to right justified text, animate the Start value from zero to 100%, and Advanced/Units to Lines. Add this expression to the Range Selector 1/Position property:

// Must be Right Justified text
s = sourceRectAtTime();
x = s.width;
[x, 0]

Add a second text animator for Opacity, set Opacity to 0%, and use a pickwhip to tie the Start value of Animator 2 to the Start value of Animator 1. Set the Advanced/Smoothness in Animator 2 to 0% to make the letters pop on.  

This is what you get:

Then, do yourself a favor. Select both Animators and save the setup as an animation preset so you can use it any time you like.

Add a second animator then and apply it to the Position property using a Ramp Down falloff to push it to the left. You'll only require a bit of experimentation to figure out the timing.

I'm still not sure what specifically you need to know. This is literally as trivial as switching the default Typwriter preset that comes with AE to "Word" in the Advanced settings and reversing its animation direction by switch Start/ End values and changing the falloff type.

Not sure what you are asking. This is perfectly possible but you have not explained what your problem actually is in the sense of what you have actually tried.
