Request to make substitution for hotkeys

For example, there is such hotkey Opt+[, Opt+1, Opt+/ or Opt+C.
It would be good if the user could create an additional substitute for such hotkeys (for example, for those hotkeys that did not work in his keyboard layout or are not convenient for him).

Perhaps the existing user hotkeys settings program could be adapted for this?
