It's not possible to move keyframes, so you have to delete the key (Bin icon) and re-set the key at a different time.
In some cases, it's easier to work with the Advanced Move Effect
in smaller animations by using two or more clips. It's like compositing or making images with a number of layers. Break the animation down in to parts, and have smaller clips timed so that the render, and what the user sees, still looks like the same overall animation. Just passing as a comment here for consideration, not suggesting it's something needed for your animation
