Short description of error
Found this string 'Paste Flipped' in the 'Blender.pot'

and was trying to translate it, so decided to investigate a little on its functionality. Created a small animation of the cube, as in this file:

and here is the clip of a screen-cast of the investigation:

I don't understand what is differences between 'Paste' and 'Paste Flipped' in this context. I simply selected the whole range of keys and move the play-head ahead on the timeline, the tried to 'Paste' and 'Paste Flipped', and they both appeared to give an identical result. With the 'Paste Flipped', I was expecting to see the reverse of the action placed down, beginning with the cube in the highest position and moving back downward to the original position, opposite to what it was before. This is potentially NOT a bug, but a TODO, perhaps?

I have produced a new test case using two shape keys of the cube:

and was expecting the 'Paste Flipped' will help me to flip the movements on an Axis, whether X or Y, but the pasted result is identical to the original. I don't really see the use of this function myself.

Paste Flipped is for armatures with symmetry, to apply to the left or right side.
