[REQUEST] Support vim keybindings for faster moving: C-d, C-u, C-f, C-b, {, }, [[, ]]

Is your feature request related to a problem? Please describe.
I found that commands like G and gg work as expected and it's a pleasure to be able to move at the top or at the bottom of the processes list.
But I'm always frustrated when I'm unable to move faster between processes using standard vim keybindings:

• jumping half page up / down
• jumping page up / down
• jumping to the next process in the process tree

Describe the solution you'd like
I offer to mimic the general vim keybindings for moving faster:

• jumping half page up / down - Ctrl-u, Ctrl-d
• jumping page up/ down - Ctrl-f, Ctrl-b
• jumping to the next process in the process tree - could be achieved using { and } or [[ and ]]
• jumping to the next node of the same level - could be achieved using { and } or [[ and ]]

Describe alternatives you've considered
None.

IMHO j and k to move down and up in the procs list would be nice too. I was surprised just now when I've tried using these and was suggested to kill a process 🙂
