introduce space and shift for up and down :)

Finally! q and e were so annoying.
I may eventually remove or reassign them to something else.

You have been warned.

PS: Yeah, like anyone but me reads this anyway :D
    so watch out, future me!

PPS: today I enjoyed reading lengthy commit messages from two years past
     me, so go figure ^^
