Additional capabilities can be added to MindManager through the use of MindManager Macros. Macros differ from add-ins in that they are not separate applications: they are a set of commands that direct MindManager to perform certain actions. Macros, like add-ins can be provided by Mindjet or third-party vendors, but they can also be created using the Macro editor provided with MindManager.
To add, delete, and modify macros on the Developer tab, click the Macro arrow, then click Organize Macros.
On the Developer tab, click Macro, then click Macro Editor.
The editor comes with its own Help file SBE6_000.chm, that is installed in top level of the MindManager installation folder. Double-click this file to see the Help.
