Click the "Enable Macros" button, and you'll notice a document that contains a table of the list of macros.
You can navigate to the actual macros by selecting Tools->Macro->Macros (Alt+F8), or for those who want to utilize VBA, by selecting Tools->Macro->Visual Basic Editor (Alt+F11) from the Word menu.
In order to make MyMacros.dot available whenever you start Word, place the file in the Start Up directory (typically, C:\Program Files\Microsoft Office\Office\Startup), which will make it a global template.
Enjoy!
