Someone asked for the functionality to change multiple fcurves at once (f.e. Loc X, Loc Y, Loc Z).
Now I managed to get all selected Fcurves in an array but I can't find any way to change their values.
There is the
bpy.types.FCurve.evaluate() method which only reads the given value at a frame.
How could I change it(optionally at a specific frame)?
EDIT: Found a workaround and posted it as solution.
