Mapping Signal.list to keyboard

I’ve done a lot of searching but can’t figure out which signals
correspond to which keyboard characters. The only one’s I’ve figured out
INT - ^C (based on a sample on another thread)

However, I want my ncurses app to use ^Y, ^Q, ^S etc and these are being
used by Unix itself.

I tried “stty -a” but the codes it gives don’t correspond to anything i
can map. e.g. ^Y = dsusp.
