scanning for a word in text window

[nate]

Im trying to make a function that looks for a certain word or words in a text window and then preforms a action, lets say shutdown macro.


there will be more winows open so i need to make sure it just scans in that window.

I will be scaning 2 or more different windows for that text at the same time, so ill need multipy functions running.
I dont want to type in the name of every window into the function so is there like a way to identify the window that i want the macro to scan. like the order they are placed on the sceen..
like function 1 scans for text in window 1 and so on

I know its a simple function, but i suck at it, someone please help

and oh the text in that window is gonna change constantly. like msn messanger, you know. so i need the function to watch that window all the time. and the window does have an id.
