I have enabled the VIM keyboard mapping and find it really useful.
Unfortunately, a few things don’t work, but that’s not so bad.
When I activate the preview with a shortcut, I can no longer scroll like in VIM but have to reach for the mouse/touchpad.
In browsers (Safari, Chrome…) there are VIM extensions that allow navigation in the browser with VIM keyboard mappings. e.g.:
d / u : half page down / up
j / k : line by line down / up
f / F : select links (upper case = in new tab)
H / L : Back / Forward (like the ← → arrows on top/left in the window)
gg / G : document start / end
/ ? : Search (Forward, Backward)
And other navigation options with VIM.
Example see: https://www.youtube.com/watch?v=bp9LtAeKqAw
So you could activate the preview with command+E and scroll with keyboard, open left, go back, …
Would be great.
Oct '20 bands requests a similar suggestion. I could not find the extension mentioned there.
