What's Wrong?

I define a keyboard shortcut of my own on VSCode, Shift+Alt+u, to the command workbench.action.toggleMaximizedPanel.

However, when Claude Code's chat pane is open it does not work, even though the key combination is not explicitly bound to any of the functionalities of Claude Code, as can be confirmed in Ctrl+K Ctrl+S.

What Should Happen?

I wold like the keyboard event to be properly passed to VSCode to invoke workbench.action.toggleMaximizedPanel command.
