Summary: This adds several 5C/5D escape codes that allow moving forward/backward words similar to bash command line navigation. On my terminal, `ctrl+v ctrl+<left arrow>` prints `^[[1;5D`. However, it seems inputrc also maps other escape variants of this to forward/backward word, so I've included those too. Similar for 5C = ctrl+right arrow.
