As the tittle says, I present you this very unknown program, which is pretty handy and helps me a lot during my DotA gameplay.
So basically, you can start the program whenever you want, before starting W3, after, or during. Window like this will pop-up:
There you press Function -> Custom Dota Key
Each clickable item in Warcraft 3 carries a number, you will have to remember that number and find it in the program. Then by adding any number to that letter, you will have a nice handy shortcut. After adding letters, you must press [END] button in the game, in order to active the shortcut. Sometimes it lags, so you must press [END] several times and remember to test the shortcut, if it works. Because in fight you will have not time for testing.
Example: If Dagon is number 4, I will no more have to use number 4 on Numeric keyboard or click on it and then target the victim, I will just simply press W key, and shoot somebody.

ps. it says it is Garena Hack, but it really isn't. It is simple Dota Helper. And it works everywhere.
