Keyframe changes/moving

How do you move the keyframes once you add them? I want the T-pose to last a wee bit longer but I already set up the keyframes thus I much prefer to select the keyframes I would like to move and move them. I could add it to the animate lite but I am not everything resets when I do that and I am not dealing with that situation again. Twice I was fooled but a third time no. Also, I accidentally add ed morphs to the last keyframe so anyway to take those morphs and put them at the beginning so they last the entire time I honestly only now knew this was a thing. I guess I could if I must delete the T pose morph and add it where I want but still, the other keyframe needs moving.
