Can you describe what you think is the difference between Ki and the syntax tree based selection expanding that's been available in emacs for probably a decade or more?

Do you mind sharing the Emacs package that does "tree based selection expanding" so I can better highlight their differences?

I haven't been active in Emacs world for a couple of years, but https://github.com/magnars/expand-region.el has been there for a while. I think the new code is right in lsp-mode and called lsp-extend-selection.

VSCode has "Expand Selection".

Mathematica has ctrl-. (http://xahlee.info/emacs/emacs/syntax_tree_walk.html)

Zed has "select enclosing symbol" but that seems to jump to function level expansion immediately, I didn't see anything more gradual there.
