You keep talking about the chosen solution scheme in general (“I want
to scroll a single cell in a {tree|list} box, and without using a
scroll bar at that”) but I think it would be useful to see the problem
that led you to this scheme.

What is your application? What are your left and right columns? What
are your rows? Why is it that only one right column in one particular
row needs scrolling? Maybe even provide some sample texts.

You also mention some input device constraints (no mouse, limited
buttons) — how is your device going to be used?

After you answer these questions, maybe someone will suggest a
different presentation.
