separate scrolling options for the left and righ panes

[Nomad-0]

Is your feature request related to a problem? Please describe. To scroll in a result's preview pane (especially in web preview), I have to use left arrow to go to the right pane, then scroll. I again have to use right arrow to scroll in the results pane again, if there were separate scrolling buttons, we could use them simultaneously without the need to constantly change panes.

Describe the solution you'd like ctrl+i/k for the left pane and arrow keys for the right or vice versa, could be quicker.

Describe alternatives you've considered Make customizable navigation controls for both the panes as requested in here and here
