Concatinating

How would I be able to add something onto the end of a trigger? For example:

Trigger: "You see a young boy."
Output: "You see a young boy. -> (Kill It!)"

I want to add on the "-> (Kill It!)" part to the trigger I read in. When I use Note() and print() it puts it on a new line though :(

The simple way is to omit the whole line, and then put the original line in the note, eg.

Output: "%0 -> (Kill It!)"

The %0 means "the entire matching text".
