Flip on X or Y axe only

[Oddity]

Hi,
I wondering if there a script to flip vector only on one axe.
The idea is to animate a shape from a side ( for exemple a head turn to the left) and get the same the other side ( and have the same head turn the other side)

You don't need any script for that - there's a flip button on top of project window while you've selected the translate tool (1).

You're right.
But i didn't explain really well what i need.
I fact i just thinnk it's impossible.
I'm gonna continu to do that vertex by vertex.

Thank you
