[CLI] only basic readline key bindings implemented - would like others

[aganse]

would like others like bash has, like alt-f/alt-b to move fwd/back one word, and alt-u for undo, etc.
note I've got some details in separate notes for possible approaches to try...

here's a link to a full list of standard readline key bindings, as experienced in e.g. bash. if ultimately have to, could maybe at least explicitly add several highly-desired bindings from this list: http://readline.kablamo.org/emacs.html
but preferably there's hopefully maybe a way to get all that through some sort of extended-defaults setting in the readline package?
