It is my first attempt at making a custom command...

1) Close down MoI
2) Unzip this file into the MoI's commands directory
3) Add a line D=CustomDistance to [Shortcut Keys] section in the moi.ini file,
   which you can find in C:\Documents and Settings\[your login name]\Application Data\Moi\moi.ini
4) Start up MoI and press the "d" key.... follow a prompt...
