SearchEditor: Open new editor with args

[wansa9]

I'd like to define a keybinding to open a new search editor with args like workbench.action.findInFiles. The following is what I want to define:

    {
        "key": "ctrl+shift+g",
        "command": "search.action.openNewEditor",
        "args": {
            "query": "${selectedText}",
            "filesToInclude": "${relativeFileDirname}"
        },
        "when": "editorTextFocus"
    }

Context: I work on a project which has a lot of files and directories. "Find in Files" takes a long time so I want to limit search target under a specified directory. #95420 is similar but I want to open search editors for different directories so "search.searchEditor.experimental.reusePriorSearchConfiguration": true doesn't fit my cases.

search.action.openNewEditor and search.action.openNewEditorToSide can now be called with args like:

{
	query: string,
	includes: string,
	excludes: string,
	contextLines: number,
	wholeWord: boolean,
	caseSensitive: boolean,
	regexp: boolean,
	useIgnores: boolean,
	showIncludesExcludes: boolean,
}

Note that while "query": "${selectedText}", works, the ${selectedText} variable throws if there's no selected text. By default search editors use selected text anyways, so you can just leave this out to use selected text if it exists and nothing otherwise.

I note that there is no intellisense for the args as of

Nor is an error indicated if I omit the args key as in

   {
      "key": "alt+g",
      "command": "search.action.openNewEditor",
      "query": "flatten",
      "regexp": true,
    },
