Need a keyboard shortcut to disable and enable copilot suggestions

Sometimes copilot suggestions may not be relevant for the file being opened.
It would be good to have a default key binding to enable and disable copilot suggestions.
Ofcourse I can define a custom one. But this seems to be basic feature and must be available widely.

該 issue 未指定任何檔案、測試或進入點。先找出 Neovim 外掛現有的 Copilot 啟用/停用命令和按鍵對映，然後確認預設快捷鍵可以切換建議，同時不會阻止自訂對映。
