Describe the bug I want to unshadow the Quick Text Search command (ctrl+shift+p):

{
    "vim.normalModeKeyBindingsNonRecursive": [
        {
            "before": ["<C-S-p>"],
            "commands": ["workbench.action.quickTextSearch"]
        }
    ],
    // other settings...
}

Vim does nothing.
