Step by step guide
What this will do is help remap the hotkeys for the item slots which are numpad(7,8,4,5,1,2) to numbers directly in front of you. Read on to learn more.
Step 1
Download the program autohotkey from here: http://www.autohotkey.com/download/
You'll need to install it, but if you rather not (ie. you just want to try it out like I did), you can choose the zip download instead and just extract the archive.
Step 2
Run the autohotkey program.
A popup box should appear asking if you would like to create a sample script, click yes.
Step 3
A txt document in notepad should have popped up with a load of text inside.
Replace
--------------------------------------------------------------------------------
#z::Run www.autohotkey.com
^!n::
IfWinExist Untitled - Notepad
WinActivate
else
Run Notepad
return
--------------------------------------------------------------------------------
With this:
--------------------------------------------------------------------------------
#q::Run C:\Program Files\Warcraft III\Frozen Throne.exe
3::send, {Numpad7}
4::send, {Numpad8}
5::send, {Numpad4}
6::send, {Numpad5}
7::send, {Numpad1}
8::send, {Numpad2}
--------------------------------------------------------------------------------
Then save your notepad and if you have to restart the autohotkey program.
Basically what you've done is remapped numpad 7 & 8 with the number keys 3 & 4 in front of the main typing space where the letters are.
The hotkey Windows+Q will also start warcraft3 should you have installed war3 in it's default location.
This should help make it easier to press them when you're panicking in the middle of some mad-ass battle scene.. haha
If you're not satisfied with the custom keys i've defined, you can change them accordingly to suit your own needs. (For example if you want to replace the number 3 with the letter q, then just replace the above accordingly)
