Issue Type: Feature Request

I'm a collaborator of vscode-leetcode extension, and frequently there are rookies asking how to bind 'test' or 'submit' command to a specific key binding, like this issue.

If we can show a message to tell them how to do it, and an option to guide them to a pre-filtered keybinding editor like this:

Then the issues about it should be reduced.

The same goes for settings editor(solved in @rebornix 's e5c1c22), where our webview uses built-in markdown preview settings to control its appearance. If we can open the settings editor with pre-filtered query 'markdown.preview', then users would find it easy to modify the settings as they want.

Some early investigations are covered in #72352 (comment), which might be of some help.
