Have you ever tought about how ppl write so fast and many messages? Well, I shall show you how to do the same!
So, go to the folder where you installed Steam and Call of Duty Black Ops.
(ex. C:\Program Files\Steam\SteamApps\common\call of duty black ops\...) Open the folder 'players' and 'config_mp'
In the part of 'bind' make a new line and write something like this: bind H "say Hi_All"
Don't forget the " " it's necessary for making a command and the ' _ ' in place of a normal 'Space' <--- It's important otherwise the command will not work.
At last you start the game and enjoy it by klicking the key you binded (but don't spam please).
You can also add some colors to your message.
The colors that you can use are:
^1 = Light Red
^2 = Light Green
^3 = Yellow
^4 = Dark Blue
^5 = Teal
^6 = Pink
^7 = White
^8 = Grey
^9 = Brown
^0 = Black
^@ = Cinnamic
^= = Light Blue
^; = Dark Green
^: = Dark Red
^> = Light Grey
^< = Orange
^? = Purple
