Moving anim weight keys in matinee curve editor and anim track at the same time

I creat anim track and activate it via setting values 0 to 1 at curve editor. And kept changing it’s value for anim blending several times. (of course I’ve set animtracks with muiltple animation sequences)
So I ask a question, how I can move my anim sequences and curve value keys at the same time after I select all the keys I want?

I was moving them seperatly but it is not efficent way. Please help me how.
