Is your feature request related to a problem?

As some streamers now use the Notes tab to describe builds in great detail (e.g. Zizaran here), I think it would be great to be able to search through Notes.

Describe the solution you'd like

I would like to have a search box in the Notes tab that searches the text within and can be auto-focused via pressing Ctrl + F as this is a well-known key binding for searching through text.

Describe alternatives you've considered

I guess the same functionality may be achieved by selecting the entire Notes tab's content, copying it into your favorite editor and using the search function there.

Additional context

Please find below a quick mock-up of what my proposed solution could look like (note the search field in the top right corner).

Empieza localizando la implementación de la pestaña Notes y sus puntos de entrada para la representación de texto o la introducción de texto. Comprueba cómo se gestionan los atajos de teclado y, después, verifica que Ctrl+F enfoca un cuadro de búsqueda y encuentra texto dentro del contenido de Notes; el mock-up del issue muestra la ubicación prevista.
