THE MACRO MOD TUTORIAL

The mod: HERE
http://www.minecraftforum.net/topic/467504-151-macro-keybind-mod-0982-and-liteloader-for-151/

• Download Liteloader. Link to download in the Minecraft Forum thread
• For Windows follow the steps 3, 4 and 5 below.
• Open your minecraft .jar with WinRAR or 7-zip:
  • Click Start -> Run (if you don't see "Run" try holding down your "Windows" key and press the R key)
  • Type %APPDATA% and click OK
  • Open .minecraft and then bin
  • Open minecraft.jar using WinRAR or 7-zip
• Delete the META-INF folder
• Drag all the files from the liteloader .zip into your minecraft jar

Now that you have liteloader...

• Install LiteLoader
• Download the .litemod file for your version of minecraft here and save it into your "mods" folder (create the "mods" folder if it does not already exist) NOTE: Some browsers will change the file extension to .zip when downloading, if this happens be sure to change it back to .litemod or LiteLoader will not find the mod!
• Run the Minecraft client
• Check the Controls screen in the Minecraft configuration to make sure there are no conflicts with other keys you use. This mod adds pages to the Controls screen for enhanced configuration of any mods which add custom keys.

Here is a tutorial of what to do when you get it
