  Adobe has this:

  on its site. However, this quite limited for a longer text.
  As far as I can tell, both the X and Y properties change over time in some prederminate way, but past the last keyframe, if I want the text to move more, I have to play with both X and Y (especially the Y) to make sure it doesn’t “droop”.
  Do you think I could instead control this with and expression?

  Does it just move in a straight line? If so, you should be able to make the y value depend upon the x value if you get the slope of how much both change.

  For example, if X moves from 100 to 300 and Y moves from 201 to 251, then your formula would be:

  Y=(X-100)/200*50+201;
