hero kill texts

[Jeeyo]

i already posted this kind of tread(i think its just last week) but i didn't get much replies that i wanted so i'm asking it again.how do you make a trigger where a text will appear when a hero kills an opponent hero twice and another txt will appear when the killing hero killed an enemy hero thrice etc.(this is just like Dota's killing spree,mega kill etc.).
