When should I use forward and move?

Question

I have a code that operates on a vector:

template
void doVector(vector& v, T&& value) {
    //....
    v.push_back(value);

That video, IMO, has the best explanation of when to use std::forward and when to use std::move. It presents the idea of a Universal Reference which is IMO an extremely useful tool for reasoning about move semantics.
