Cubase LE 5 Mastering Question

When I want to increase the volume on just a portion of a single track, the only way I know how is to split that portion of the track, then go into the Process option to select “Gain,” then I boost the Gain a bit. Is that purely just increasing the volume? Or is there a better way to do this?

Automation

Could you elaborate please?

Open Cubase -> Press F1 -> in the PDF read the chapter “Automation”, then ask if and what you don´t understand.
