Can I shift all the keys to the right after a set time in the animation?

[jblower]

I have set up an animation but I need to take everything after frame X and shift it Y frames to the right so I can input a guy moving.  I don't know how to do this without changing each and every little thing.  How would I do this? So I want to take everything at time=3s and move it all to start 3s later.

There are a few ways:

1) If the 'Time Slider' is open in the main workspace, just select all the objects that have the keys you want to move and then 'region select' the keys in the timeline. Then click and drag them to the right. 

2) If you open 'Curve Editor' (right click on an open space in a viewport) you have access to tools that you can use to select the keys and then slide them over. You also have more tools there as well. I'd suggest Googling and doing a tutorial on 'Curve Editor' if you really want to learn it better. It's powerful and good to understand.
