 - 本轮补充：keybinding config、keymap 解析和 interaction script named-key 输入接受 `ctrl-h`/`ctrl-i`/`ctrl-j`/`ctrl-m`、`ctrl-[`、`ctrl-?`、对应 `control-*` 以及 compact/camel 形式；terminal parser 支持 CSI-u/kitty keyboard protocol 的 ctrl/alt/shift-enter/shift-tab 序列；image hint parser 支持 OSC ST terminator 和 base64 `name=` filename；keybinding JSON loader 支持 wrapper object-map、`shortcuts`、object action 字段、string-array key sequence/chord 和 `null`/`false` unbind；mouse parser 支持 legacy X10/normal tracking 序列；interaction script 支持结构化 mouse/mouse_event 步骤，button 接受 `buttonMask`/`button_mask`/`btn`/`code`/`mask`，坐标接受 `mouseX`/`mouse_x`/`clientX`/`screenX`/`pageX`/`offsetX`/`viewportX` 和对应 Y/row/line 别名，release 接受 `mouseUp`/`isRelease`/`mouseRelease`/`releaseEvent` 等字段别名；interaction script 还支持字符串 `keys` 和 `input`/`input_text`/`keys_text`/`raw_key`/`paste_text` 字段别名，并允许 status/snapshot/viewport/pasted-content contains 断言使用单字符串或字符串数组，`keybindings`、`expectEvents`、`expectDialogResults`、`expectPrompt.pastedContents` 和 `expectTasks.contains` 使用单对象或对象数组。
 - 本轮补充：keybinding config 的 page/navigation/editing key name 现在接受 `pgup`/`pg-up`/`prior`/`pageUpKey`、`pgdn`/`pg-down`/`next`/`pageDownKey`、`homeKey`/`endKey`、`deleteForward`/`forwardDelete` 和 `deleteBackward`，覆盖常见终端、DOM 和配置别名。
 - 本轮补充：keybinding config 和脚本 named-key 输入接受 DOM-style arrow key aliases，包括 `arrowLeft`/`arrowRight`/`arrowUp`/`arrowDown` 以及 ctrl/alt/meta/option arrow variants。
-- 本轮补充：keybinding action parser 接受更多 editor/global-style action aliases，包括 `cursorLeft`/`cursorRight`、`lineStart`/`lineEnd`、`deletePreviousChar`/`deleteNextChar`、`killLine`、`pasteKillRing`/`yankPrevious`、`clearScreen`、`openExternalEditor`、`toggleTasks`、`cancelAgents`、`focusPrev`、`acceptSelection` 和 `search`。

 - 本轮补充：keybinding config 和脚本 named-key 输入接受短修饰符别名，包括 `c-`/`m-`/`a-`/`opt-`/`s-` 以及 compact/camel 形式，可覆盖 control、meta、alt、option 和 shift key names。
 - 本轮补充：keybinding config 和脚本 named-key 输入现在接受 `backtab`/`back-tab`/`btab` 等 Shift-Tab terminfo/fixture 别名，并映射到既有 focus-previous key surface。
 - 本轮补充：keybinding JSON loader 现在递归解包 `data`/`payload`/`settings`/`config`/`keyboard`/`keymap` 等外层 wrapper，嵌套 preference export 中的 `bindings`/`shortcuts` 不需要手工扁平化。
