changing keyframe value with expression

[GeorgeK001]

How can I give a value to the second keyframe depending of the text length?

The first key frame is static but want to move the shape to the right to cover the text.

I also want to keep the characteristic of movement, so the linear(t,t1,t2,x,y) doesn't suit for this.

Thanks for any help

You still use linear() to modulate the output, only this time actually remapping the time paramater that feeds into a valueAtTime() construct.

thanks for this, could you give me an example please?

Once you have time I would need an exapmle as the code I used actually didnt work.

Thanks in advance
