Triggered macros

Would be amazing to have different macros being triggered automatically when a player says or rolls something specific in chat. Or draws a particular card from a deck. Or steps on a particular location on the map. etc etc etc

The first one I'm not sure why you'd need it as you CAN type #macro in chat and have a macro roll. :P But having macros act on conditions like "When another token stops in an area covered by another token on the GM layer" OR to have an attack macro that could trigger a damage macro on or greater/lesser than a particularly roll OR have a macro call from a list of possible options and only report one based on the roll.

I understand you CAN type the macro already but on the off chance that one of my players cusses in the chat window I'd like a penalty roll to be made automatically. Or perhaps each game session I have have a word of the day that sparks something magical. Never doubt a GMs capabilities. The more options available to us the more havoc we can cause our players ;) There are lots of interpretations of "triggered macros" was just a general suggestion after hearing it discussed during the live question and answer session the other day...
