text in a structured way. They allow you to refer to blocks of text based on

< p > Navigating between functions, classes, parameters, and other elements is
possible using tree-sitter and textobject queries. For
example to move to the next function use < code > ]f< / code > , to move to previous
type use < code > [t< / code > , and so on.< / p >
