求助：VSCode搜索输入框光标命令快捷键无法修改的问题

我在修改VSCode的快捷键配置时，遇到了搜索输入框光标相关命令无法生效的问题。以下配置的ctrl+b快捷键在编辑器文本获得焦点时可正常触发cursorLeft命令，使光标左移：

{
    "key": "ctrl+b",
    "command": "cursorLeft",
    "when": "editorTextFocus || searchInputBoxFocus || inSearchEditor || searchViewletFocus"
},

但当光标处于搜索输入框中时，该快捷键毫无作用，仍需按左箭头键才能移动光标。

请问是否存在适用于搜索输入框光标移动的其他命令或特定when条件？

补充信息 #

在快捷键调试中，在文本编辑器按下左箭头键时，光标左移，输出显示触发了cursorLeft命令：

[KeybindingService]: / Received  keydown event - modifiers: [], code: ArrowLeft, keyCode: 37, key: ArrowLeft
[KeybindingService]: | Converted keydown event - modifiers: [], code: ArrowLeft, keyCode: 15 ('LeftArrow')
[KeybindingService]: | Resolving [ArrowLeft]
[KeybindingService]: \ From 10 keybinding entries, matched cursorLeft, when: textInputFocus, source: built-in.
[KeybindingService]: + Invoking command cursorLeft.

而在搜索输入框按下左箭头键时，光标虽左移，但输出显示无匹配命令：

[KeybindingService]: / Received  keydown event - modifiers: [], code: ArrowLeft, keyCode: 37, key: ArrowLeft
[KeybindingService]: | Converted keydown event - modifiers: [], code: ArrowLeft, keyCode: 15 ('LeftArrow')
[KeybindingService]: | Resolving [ArrowLeft]
[KeybindingService]: \ From 9 keybinding entries, no when clauses matched the context.
