I suggest having hotkey for in-game summary and replaymenu summary as Ctrl + Alt + S.
Changing therefore silhoutte hotkey to Ctrl + Alt + Shift + S.
Switch to next tab hotkey in summary, credits and options page (so generaly) Alt + S.
and switching to previous tab hotkey Alt + W.
Remember showed panel and showed charts for next opening.
