How to create cross-platform keyboard bind commands?

view story

http://unix.stackexchange.com – I'd like to have the same keyboard shortcuts in all the terminals I use. Since they don't have the same *nix on them, and since terminals can be very different, I'm looking for a reasonably portable way to get keyboard shortcuts from one *nix terminal (at least supported by a standard Ubuntu 12.04 installation) to other terminals (Bash only). (HowTos)
