replace "trigger word" with the word that is to trigger it.. "*" means "anything" that matches after it. It's a wildcard.

trigger: hello *
hits: hello out there, hello all

trigger: howdy (without the *)
hit: howdy
NON hits: howdy (with a space or ANYTHING else after the word "howdy")

it's necessary for it to work properly.

iswm = is wild match
