Macros
Initially, everyone will start with one set of macros, but as time goes on you can design multiple sets of macros. Using the import and export functions, you can copy macros from one file to another. Examples where multiple macro files might be handy could include specialized projects, non-cataloging projects involving other applications, or macros specific to a particular cataloging format, among others. Doing this might help in organizing your macros better and prevent cluttering up your main set.
You can switch between macro files by either clicking on the Open Macro File button from the toolbar or selecting Open Macro File from the File menu. In the File menu, the Reopen selection will have a list of the seven last macro files you had opened. Clicking on the arrow just to the right of the Open Macro File button does the same thing. If, for any reason, you shut down your computer (i.e. it didn't crash), Macro Express will remember the last macro file you had opened.

You can also create a new macro file from scratch by either clicking on the New Macro File button from the toolbar or selecting New Macro File from the File menu. When you create a new macro file, you will have a blank macro file with the exception of six system macros that Macro Express requires in each macro file. From this point, you can start adding macros from scratch or import macros into your new macro file.
