I see how one can create a new trigger using the GUI, but not modify an existing one or delete one. Yes, I am aware one can do so via mysql statements, but, that's the purpose of Heidisql too, to avoid having to know all the syntax.
I see a post from HeidiSQL long ago, which I cannot post a link to as I don't have authorization yet, but it's on the heidisql site and has screenshots.php?which=trigger_editor in it. It says create and modify, so, I am thinking modify must be a function, I just can't find it! Can anyone direct me to where in the GUI to modify an existing trigger, or even see it?
