## What it is
A (Neo)Vim plugin that automatically highlights other uses of the word under the cursor using LSP, Tree-sitter, or regex matching. It includes keymaps for navigating between references and a textobject for the illuminated reference.

## Use cases
- highlight all occurrences of the word under the cursor in vim
- navigate between references of a symbol in neovim
- highlight variable usages using LSP or treesitter
- see where a function is used in the current buffer
- automatically illuminate matching words while editing code

## When to choose
- you use Vim or Neovim and want automatic highlighting of symbol references without manual searching
- you want zero-config highlighting that leverages LSP or Tree-sitter when available
- you need keymaps to jump between occurrences of the word under the cursor

## When to avoid
- you use an IDE or a non-Vim editor with built-in reference highlighting
- you need project-wide reference search rather than buffer-local highlighting
- you work with very large files where the plugin disables itself by default
