Need help with ctrl + backspace command

I am using the trial version of IT with EditScript. I am needing help with creating a command to delete 1, 2, etc. word/words at a time. Normally, I would use ctrl + backspace for this, but I wanted to create a short for it. I tried, {command}{Ctrl Backspace} but this only deletes one character at a time or just a couple of characters at a time, never the entire word. Any help with this would be appreciated as well as any other command ideas to be used in EditScript. I read an older post where there is a command list that can be used in this platform. Do anyone have it?
