## Tree-sitter Based Navigation
Navigating between functions, classes, parameters, etc is made
possible by leveraging tree-sitter and textobjects queries. For
example to move to the next function use `]f`, to move to previous
class use `[c`, and so on.

See the [unimpaired][unimpaired-keybinds] section of the keybind
documentation for the full reference.
> NOTE: This feature is dependent on tree-sitter based textobjects
and therefore requires the corresponding query file to work properly.
