SharePoint Tip - Shortcut to 12 hive with ease

I have to go to 12 Hives from command prompt so often that i looked for a better
solution to reach there . Here is what you have to do:
(1) Create a new text file in notepad and write the path to 12 hives like this :
cd C:\Program Files\Common Files\Microsoft Shared\web server extensions\12
(2) Save the file as 12.cmd
(3) Copy the file and put it inside c:\Windows folder
(4) Job done... from anywhere in command prompt as soon as you press 12 , you get to
12 hives of sharepoint..
