# CodeEditor ## `` - `mode` (xml, html, css, js, json, text), `footer`, `modeselect`, `readonly`, `update-enabled`, `reformat`, `validate`, `highlight` - actions: focus, activate, unbind - events: Updated, Changed, Saved, OnInput, Select, ContextMenu, SelectionMenu, ValidXml, InvalidXml, MimeIsXml, MimeIsNonXml, XpathResult, LastUndo, EnableUndo, LastRedo, EnableRedo, Drop - methods: updateData, setUpdateEnabled, reformat, search, searchAndReplace, searchCount, clearHighlights, takeEnter, releaseEnter, gotoLine, setCursor, highlightNode, getSelectionValue, getSelectionXPath, haveSelection, setFont, executeCommand, doCopy, doCut, toggleComment, deleteNodeAtCaret, emitCtrlZ, emitCtrlY ## Guidance ```xml ``` - The bound document's type picks the mode. Edits are written back on leaving or after a second's pause: before a Save, call `updateData` with `wait="true"`, as above. - `readonly="true"` shows only; `update-enabled="false"` edits without writing back. No enable/disable; `highlight` has no effect. - Changed can fire several times per edit - treat it as "check the document"; ValidXml/InvalidXml follow each update. - `label` is its only accessible name. Tab indents; Escape then Tab leaves - say so in a help text.
