How to delete current word in nano text editor?

Save this file to ~/.nanorc and ctrl+] cuts the word to the left, and ctrl+\ cuts right

This works for me in nano version 2.5

bind    ^]          cutwordleft         main
bind    ^\\         cutwordright        main

This works for me in nano version 2.9.3

bind    ^]          cutwordleft         main
bind    ^\          cutwordright        main
