Use Ctrl/Meta-4-f to move 4 characters/words forward, etc.

[maitra]

In my bash readline, I can move forward or back, and delete several characters/words at once. In particular, when I type:

Meta-4-f, I move four words forward.
Ctrl-4-f, I move four characters forward.

Is it possible to get similar behavior in this and other such scenarios.

Thanks!
