backward_word
Synopsis:
bind <key>
Description:
This function moves the cursor backward until it reaches the beginning of a
word. If the cursor is currently in the middle of a word, it is shifted to the
beginning of that word. If it is already at the beginning of a word, or on whitespace
of any kind, it is moved back to the previous word. It has no effect if the
cursor is at the beginning of the first word.
