Delete multiple words command

Thanks for the examples and explanation for which each one does. I finally figured out how to delete a four-letter word, but the way I have done this is way too complicated. I used {command}{Left}{Ctrl Backspace}{Backspace}{Backspace}{Backspace}_. Once again, this only works for four-letter words so not really effective. I will try your command as it is much easier. If you can think of any other commands, please send them my way. Thanks again.
