It's easy. (1)Pick the value you want to adjust (let's say Ytrans on the hip). (2)Place the cursor in the graph window, hold down right click on your mouse, and drag the cursor. A black field should be drawn on the graph. All the points in this blackened area will be affected at the same time. (3)If the field doesn't cover all the points you want, simply hold down 'Shift' and either right click and drag one side or the other to cover them, or hold shift and left click; this will move expand the black field to where the cursor is. (4)You'll notice that the cursor changes shape in the graph window depending on where it is, and what key or button you hold down. If you move the cursor into the black field, it should turn into two small, horizontal lines with arrows at either end. If you right or left click and hold while the cursor is there, and slide the mouse, you will move all the keyframes in that field left or right on the timeline, shifting a motion earlier or later in the sequence. (5)To make a vertical adjustment, place the cursor in the field, hold down control. The double horizontal lines should turn into double vertical lines. Just click in the field and move the mouse up and down (while still holding down control), and you should see all the keyframes in the area shift up and down.
