I have some vim-sexp bindings that I never use for editing, and I would like to free them up for other things - namely <M-j> and a few others. Anyone know how to do that? EDIT: As usual when asking a question I then went and read the :help and it was here: https://github.com/guns/vim-sexp/blob/master/doc/vim-sexp.txt#L609
