Knowing the workspace and workflow of an editing software

I would like to know the usage of customizing the Project Panel. What are the common default shortcuts that we can use to make it easier and faster for us to edit videos? What is Adobe dynamic link? What do you mean by cross-application? What about cross-platform? Can I customize keyboard shortcuts in Premiere? What are the shortcuts for trimming a project? What is the view of its timeline? How to import and export files in this software? Please help me! Thank you!
