Consider more conventional tree navigation behaviors

[mholt]

I find it helpful when navigating any tree structure to be able to collapse and expand all nodes, but also go <-- (left) and --> (right) to move into & out of the structure's depth.

Right now, LEFT and RIGHT arrow keys only go UP and DOWN, but would you consider having LEFT and RIGHT jump directly to the adjacent parent/child node in that direction?

Also, the key bindings are really unintuitive for non-vim users. Could we consider using SPACEBAR and SHIFT-* (etc.) for certain actions like expanding/collapsing current node, jumping up or down a page or element, etc? I don't have anything too concrete in mind, but it's a little tricky to use right out of the box. I have to keep referencing the table in the readme, but I feel like I should just be able to figure it out with my arrow keys and spacebar and ctrl/shift keys.

Additionally, the "Collapse all nodes" (H) doesn't seem to be very helpful, as it just replaces everything with a . ... which I can then edit... anyway, I just think there's some room for significant improvement here in the UI.

what it mean like following?

{object}
├──like <-- cursor in there
│  ├──dog
│  └──cat
├──name
│  └──gorilla
└──age
   └──27

using C-j jump to next key as following.

{object}
├──like
│  ├──dog
│  └──cat
├──name <-- cursor in there
│  └──gorilla
└──age
   └──27

using C-k jump to previous key.

{object}
├──like <-- cursor in there
│  ├──dog
│  └──cat
├──name
│  └──gorilla
└──age
   └──27

How about using space to expanding/collapsing, c-j and c-k to move next next or previous key?

I added help panel so you can use ? to display it :)

Yep! I think so anyway 😅

Sure, space is great.

Cool, thanks!

I see, I’ll implement :)
Thank you for the idea

@mholt Hi, I implemented following, please update tson and try it :)

• use space to expand/collapse node
• use c-j to move next parent node, c-k to move previous parent node.

If you find some bug let me know :)

Great! Nice improvements, thanks :)
