readline is used by many interactive programs (bash, python, bc, gnuplot, ...),
and so these timesaving keybindings are very useful to know, especially when working
over remote high latency links where moving character by character can be problematic.

readline is configured using ~/.inputrc

You can create your own shortcuts by adding entries like the following:
"\e[21~": "mc\C-M" #F10 toggles mc on and off

In bash `bind -p` will give a list of bindings.

readline defaults to emacs bindings but you can change it to vi mode.

`info readline` for more info.
