Would it be possible to bind left arrow / h to jump up one level in a TreeView? I can make a pull request if you approve.

I could probably add a new key binding to jump up one level. But it can't be "left arrow" because it's used for something else already. Maybe Ctrl-Left-Arrow (if that's possible). The question is also if that key binding should also cause all children to collapse or simply jump up without collapsing. Any thoughts?

Sorry for the late response.

KeyLeft currently does the same thing as KeyUp in a TreeView, right? Ctrl+KeyLeft would also work. I assume making it possible to reassign the default key bindings to allow deeper customization would entail a large amount of work that is probably not worth the effort.

For collapsing I would tend to say no, but that could maybe be a configurable setting?

I've added the "K" and "J" key binds to the TreeView which move you up and down the hierarchy, respectively. Unfortunately, there is no CtrlKeyLeft and using the key mod in tcell is apparently not reliable on all platforms.

But if you want to have your own key binds, you could use SetInputCapture() to translate them.
