do a series highlighting the different features, also explore the options menu, there is an option called "Number of opcode bytes", this will show you the hex bytes of each instruction.

The debugger in IDA is also something worth exploring.

if you highlight an instruction, IDA will tell you the offset in file that you can verify with a hex editor

IDA scripting (IDC/Python) is also an interesting area for automation
