`:lsp.hover` or a configured hover action requests information at the primary caret once, regardless of count or selection count. The response opens a read-only floating popup: arrows/Ctrl+h/j/k/l scroll vertically/horizontally, Home/End select the first/last logical line, and Escape dismisses without collapsing carets. Other input dismisses and continues normal editing. Changes to the source buffer/revision/caret, intervening input, or newer requests prevent pending hover replies from reopening it.
Hover accepts plaintext/Markdown MarkupContent and string/code MarkedString forms, including arrays. Multiline content is preserved; Markdown is shown as plain text, not rendered markup. Horizontal scrolling exposes long lines without splitting graphemes. Missing/unsupported/invalid hover results report a message without changing text, selections, or undo history. Content is bounded to 4 MiB and terminal controls are sanitized.
Hover accepts plaintext/Markdown MarkupContent and string/code MarkedString forms, including arrays. The popup grows up to 100 columns and 24 rows, clamped to the available document workspace and content height. Multiline content and Markdown markers remain visible, with the same Markdown syntax colors as document buffers; named fenced code blocks use their language's bundled highlighter. Highlighting is cached across scrolling and redraws. Horizontal scrolling exposes long lines without splitting graphemes. Missing/unsupported/invalid hover results report a message without changing text, selections, or undo history. Content is bounded to 4 MiB and terminal controls are sanitized.
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.
