(Neo)Vim has a bunch of text objects that are beyond simple boundaries other than a word (~aw~, ~aW~).
You can find more of them with ~text-objects~ section from [[id:0a0fe63e-dcf3-4928-9e82-5513784c1244][Neovim help system]].

| Text object | Description                     |
|-------------+---------------------------------|
| ~ap~        | A paragraph, equivalent to ~}~. |
| ~as~        | A sentence, equivalent to ~)~.  |
| ~ab~        | A '( )' block.                  |
| ~aB~        | A '{ }' block.                  |

There is also a variation for selecting only the inner content of the previous text objects (e.g., ~ip~ for the inner paragraph, ~is~ for inner sentence) with the whitespace removed.

Note that selecting with text objects is different from selecting with [[roam:Neovim motions]] where it refers to the current position up to the end of the next selection.
Meanwhile, text objects selection will select to the referred object as a whole no matter where the cursor position.
For example, selecting with the paragraph (i.e., ~vap~) will select the whole paragraph where the cursor rests.

Aside from the built-in text objects, you can create your own.
Which also means others have created some custom text objects.

- [[https://github.com/nvim-treesitter/nvim-treesitter-textobjects][nvim-treesitter-textobjects]] add text objects support for selecting (and swapping, moving, and peeking) tree-sitter nodes.
  (Assuming you have tree-sitter support enabled for Neovim.)
