Works the same as M-b for me (backwards-word)

Make sure your /etc/inputrc or ~/.inputrc contains

# mappings for Ctrl-left-arrow and Ctrl-right-arrow for word moving

"\e[1;5C": forward-word

"\e[1;5D": backward-word

"\e[5C": forward-word

"\e[5D": backward-word

"\e\e[C": forward-word

"\e\e[D": backward-word`

Last I tired to set one up the docker image just vomits. The install instructions are for ubuntu, but everything in my server farm is all debian and they don’t have the same versions of packages so it doesn’t work.

I could spin up an Ubuntu instance and try the manual install instructions again, but having a one off system doesn’t make me happy.
