I have this to use the arrow keys without any modifier: # Use up/down arrows to search on partially typed command bind '"\e[A"':history-search-backward bind '"\e[B"':history-search-forward Just type the first letter(s) and use the up/down arrows to scroll through the filtered command history. Incredibly convenient.
