Tweak #1
To enable arrow keys to search history for the ending of a half-typed line.
bind '"\e[A": history-search-backward' bind '"\e[B": history-search-forward'
Usage: Type something in terminal that you know is the beginning of a long command line that you occasionally need. Arrow keys up and down should complete it.

Usage: cmd; alert where ‘cmd’ is an arbitrary command that performs a process, e.g. wget.
