Sometimes the best way to learn something is to experiment with it, meaning have a play around with the software until it starts to click. It’s simply just playing around with buttons and testing them to see the functions. So it is a great idea to start early and try to develop yourself around it; and get used to navigating yourself around the software. Experimenting is the best way to familiarize yourself with the tools; as you will learn what buttons do what and then you will start to get the idea of how the software works.
There are many ways of learning the software, one of the best ways is to get instructional videos; and there is plenty of content out there that will guide you. For example, YouTube has great content and videos that will give you the instructions and tools to learn the software. YouTube guides you step by step on how to use the software; which will give you an idea of what buttons work were; it is basically a navigation tool that will show you the use of every function.
