Editing text

Every framework mounts the same web-component editor. Commands, keyboard shortcuts, search, language metadata and document conversion have one implementation.

Find and replace

Use Find and replace or Ctrl+F (Command+F on macOS) while the editor is focused. Enter a literal search phrase and use Find next or Find previous to move through matches. Match case controls case sensitivity. Escape closes the panel and returns focus to the document.

Search spans adjacent formatted runs within a paragraph. It does not match across paragraphs, table cells or hard line breaks. It avoids matches that split a Unicode grapheme, such as part of a combining sequence or joined emoji. Searches are literal; regular expressions and locale-specific linguistic matching are not supported.

Replace changes the current match; Replace all changes the document's matches in one undoable operation. Replacement text takes the first matched character's formatting. Text outside the match retains its formatting. Searching works in read-only mode; replacement is disabled. Existing DOCX preservation checks still apply when exporting edits around unsupported source content.

Multilingual documents

Paragraph direction and text language are separate properties. Use Paragraph direction for left-to-right or right-to-left layout, and Run direction for an explicit direction override within a paragraph. The language controls store Word's regular, East Asian and complex-script language tags. Language metadata does not translate text or install a spellchecker.

The editor preserves Unicode text, including Arabic, Hebrew, CJK, combining characters and emoji. Browser fonts, shaping and bidirectional layout determine the on-screen appearance. These controls do not establish Word-equivalent complex script typography, pagination or operating-system IME behavior.

Word counts use the browser's Unicode word segmentation, including dictionary segmentation for unspaced scripts where supported. Counts can differ between ICU versions and from Microsoft Word. Older browsers use a less precise fallback.

Coauthoring integration

The collaboration guide describes the versioned editing protocol and how an application connects the shared editor to its authority. This is an integration API, not a hosted collaboration service. Access control, networking, storage and reconnect policy belong to the application.

Interface language

Set the shared editor's locale property (or the binding's locale prop) to en, fr, de, es or zh-CN. Regional and script variants resolve to the nearest supported language (fr-CA, de-DE, es-MX, zh-Hans, zh-SG); unsupported locales, including Traditional Chinese (zh-TW, zh-Hant), fall back to English. EDITOR_LOCALES lists the codes and normalizeEditorLocale() maps any tag to one. Every locale defines every string key (checked at compile time and by tests). The German, Spanish and Simplified Chinese strings have not been reviewed by native speakers. Changing the interface language preserves the current document, selection, undo history and document-language metadata.

Imported paragraph styles

The Home ribbon's Style picker lists paragraph styles from the loaded DOCX. The editor resolves supported alignment, direction, spacing and indentation through document defaults and the selected style's inheritance chain. Direct paragraph formatting still takes precedence. Choosing a style changes its reference, without flattening inherited properties into every paragraph.

The original styles part is preserved when saving the loaded document. Creating or editing style definitions, character styles, inherited run formatting and theme resolution are not supported yet. Exporting a new package with a style catalog is rejected; use Save on the loaded document to preserve its original style definitions.
