Goals

Make scrolling more ergonomic and intuitive. Use j and k instead of d and u.

Same for paging, use J and K instead of D and U.

Background

j and k have been standard since 1976, are available on the QWERTY home row, and are the obvious keys most terminal users will reach for when they need to scroll in a TUI.

Proposal

Just make the change. If you're worried about backwards compatibility, you can just make j and k work in addition to d and u. You don't even need to add it to the instructions at the bottom of the pane—every Linux user will instinctively push k to try to scroll up in a TUI.
