I've got a cursor navigation problem with the editor I haven't been able to solve. I'm on a Mac running the latest version of Firefox. Most of the key bindings are emacs like using the Ctl key, but with a few exceptions. Ctl-B toggles bold instead of moving back (Cmd-B also toggles bold) and Ctl-K toggles a numbered list instead of clearing to end of line. I am a software engineer and am comfortable with Javascript, and would like to fix this, I just don't know much about Redactor. Is there a way I can customize my editor to be more emacs compliant?
