So let me get this straight: this snippet is to make a text, action or input event for you with the trigger command of your choice? If this is the purpose of the code, it's for those who are lazy to write the events manually then... This sounds may be a tad negative, but I know you want to make it easy and convenient for writing up a mIRC event.
Be aware and reminded that many novice users will make an input event like this:> on :input:THEY PUT THE MATCH-TEXT Trigger here*:#:{There is NO match text section for the input event.
