There is no easy way to do this (yet)
You will have to add a couple more keyframes at 1 sec to the LC_01, LC_02, LB_02, LCB_01 and LCB_02 and then highlight all of the keyframes (by shift clicking) and then moving them wherever you need to. You can then grab the rest of the keyframes (shift click or drag box over them) and move them too.
Here's a little video showing how to select more than one keyframe. (note ⇧⌘\ for different timeline view)
