CC3+ - Create Custom Buttons
In this video I show you the process of adding your own custom buttons to CC3+. How to create a custom menu and how to link the menu and button to a custom symbols catalogue or even link them to the existing catalogues such as the Annuals!
This is an advanced topic that involves editing files in text editors. For that I recommend and use Notepad++. It's a free open source application.
Here's the link to the Big Book of Maps that caused me to learn all this! I'm really enjoying these symbols.
