[Feature Request] Allow keyboard shortcut customization for thinking mode toggle in VSCode terminal

Bug Description
While in a VSCode terminal, it’s impossible to change the thinking mode because the terminal interprets Opt+T as Alt+T. It would be helpful if we could return to the tab to change the thinking mode.
