Support VI style keys

[pjmbox]

is it possible to support vi keys ? for example, use j, k instead of up and down arrows ? use : to switch to edit mode and enter filtering string ?

FWIW, I'm a vim keybinds user, and I tend to use Ctrl-n Ctrl-p. They're pretty universal, and most "vim style" tools like vimium support it. Even tmux supports it. I think it would be worth a try.
