Semantic highlighting is **enabled automatically** when the first server advertises [LSP semantic tokens](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_semanticTokens). No additional configuration or binding is needed. Full-document requests are preferred; range-only servers receive a whole-document range request. Token colors override Tree-sitter where recognized; unsupported servers, unknown custom token types, missing tokens, and failed replies retain syntax highlighting. Text/path changes clear old semantic colors immediately, and stale replies cannot restore them. Same-text refreshes keep the current overlay until the replacement arrives.
rust-analyzer and ty support semantic tokens. Solargraph 0.61.0 and Ruff do not; Ruby therefore retains Tree-sitter colors with the Solargraph preset, while Python uses ty's tokens and Ruff's diagnostics. Declaration/definition modifiers use bold, deprecated symbols use strikethrough, and readonly variables/properties use yellow. Diagnostics, search, selections, and carets retain their existing styling precedence.

Declaration/definition modifiers use bold, deprecated symbols use strikethrough, and readonly variables/parameters/properties use italics without changing their role's color.

Native LSP currently provides synchronization, diagnostics, go-to-definition, hover, and semantic highlighting—not completion, rename, formatting, code actions, or workspace edits. Semantic token deltas, dynamic registration, and partial-result streaming are not implemented.

Markdown heading markers (`#` through `######`, or Setext underlines) share the heading text's markup color. Plain-text hashes and other punctuation keep their existing styling.
An enabled supporting LSP server supplies semantic tokens automatically, overriding syntax colors only on recognized spans. Variables/parameters use light cyan, properties blue, and readonly variables/properties yellow; declarations/definitions are bold, documentation comments italic, and deprecated symbols struck through. Tree-sitter fills gaps and remains available while new tokens are pending after edits. Search, Visual selections, diagnostics, and carets keep their existing precedence. See [native LSP configuration](configuration.md#native-lsp) for provider support and server-stack routing.
An enabled supporting LSP server supplies semantic tokens automatically, overriding syntax colors only on recognized spans. Semantic colors also use the terminal palette: namespaces neutral gray, types cyan, variables/parameters light cyan, and properties blue. Readonly variables/parameters/properties keep those role colors and add italics; declarations/definitions are bold, documentation comments italic, and deprecated symbols struck through. Italic emphasis depends on terminal support. Tree-sitter fills gaps and remains available while new tokens are pending after edits. Search, Visual selections, diagnostics, and carets keep their existing precedence. See [native LSP configuration](configuration.md#native-lsp) for provider support and server-stack routing.
