Typical key bindings:
In order to move several 'steps' at once, the movement commands may be given a prefix argument by pressing ESC or C-u and a number before the listed keystrokes. For C-u, the number is optional and defaults to 4.
E.g. ESC 3 C-n moves 3 lines down, while C-u M-f moves 4 words forward.
