Suggestion: Add vim like shortcuts similar to fzf for navigation

[AnthonyAstige]

Idea: Add support to hit ctrl-j / ctrl-k in addition to arrow keys for selecting files. This would work like fzf.

Could go further but just those would allow quicker navigation without leaving the homerow than moving to the arrow keys.

@AnthonyAstige Can i hit Ctrl + to select/unselect the file instead of Tab. My finger is holding left Ctrl while hitting j and k, I don't want to move the finger from Ctrl to Tab and move back to Ctrl.
