On some terminals it's not possible to rebind ^H (unless -raw is used) because its keycode is identical to that of the Backspace key. Rebinding ^M (Enter) or ^I (Tab) is probably not a good idea. (Often, F13 to F24 can be typed as F1 to F12 with Shift.) But when any Shift+Meta bind is made, that willįN where N is a numeric value from 1 to 24.
