What do you mean by 'removing them all'? Remove what? From where?
You are, of course, absolutely right. Sometimes you have the problem in your head and forget that everyone else has not been included in your thoughts so far. I think m1b's answer contains exactly what I was looking for. But he too actually had to guess wildly at my needs.
Hi David, what you're asking is probably possible, but we'd need more information about your specific needs.
To get started, here's a script I just wrote that will remove behaviors with those event types from all buttons in the active document. I've made it fairly flexible so behaviors can be removed from other items and target different events. Let me know if that works for you.
