Flip last edges of Rubik's cube

flip_edges.txt

Flip last two edges in place. Front-top edge and left-top edge.

For this example, an algorithm that is more simple to remember, 
and can be altered for the other case (opposite edges), is this: 
F' E F2 E2 F' U' F E2 F2 E' F and U. 

Replace U and U' with U2 for the case of flipping two opposite edges on top face.
(E is the equatorial slice, viewed from face U)
