Bash CTRL to move cursor between words/strings

Question

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).

Can I do

Answer 1

With the default readline key bindings, ALT+B goes back one word, ALT+F goes forward one word.

The default Ubuntu setup additionally provides CTRL+arrows like you're used to. These are in /etc/inputrc and specified as follows:

# 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

Not sure why we need three of them...
