How do I forward Chrome keyboard shortcut available to a Cockpit web terminal?

Question

I am using cscope on Cockpit web terminal to browse a source code. The Ctrl+T shortcut used to unwind the tag stack is captured by Chrome/Mozilla, which then opens new tabs. Even if I remap the said shortcut to something common, like Ctrl+K, that too gets captured by the browser. How do I forward the browser keyboard shortcuts Cockpit? I used a few browser plugins that disable the keyboard shortcuts, but then those plugins suppress the shortcut altogether, neither forwarding to the browser, nor to Cockpit. Hence, those are useless.

• Tried using several Chrome plugins, none works
• Tried switching browser from Chrome to Mozilla
• Tried changing keyboard bindings
• None of the solutions captures and forwards (passes through) the keyboard shortcuts to Cockpit
