The YouTube Channel videos for beginners which start out with hotkeys, and learning the interface are based on an older model of the program, and the location/function of the buttons seem to be outdated.

The purpose for which I am using the program is to create housing and environmental structuring on Second Life.

Can anyone kindly direct me to a location that will guide me through the steps of getting acquainted with the program so that I can begin implementing it, please? Thank you all very much.
