I am use to using the ctrl key to move faster when using the left and right arrow keys (goes to end of a word, instead of one char at a time).
The file /etc/inputrc file is missing. Could you add it by default?
The content should be something like this:
# mappings for Ctrl-left-arrow and Ctrl-right-arrow for word moving
"\e[1;5C": forward-word
"\e[1;5D": backward-word
"\e[5C": forward-word
"\e[5D": backward-word
"\e\e[C": forward-word
"\e\e[D": backward-word
