This is 2.79 which is right before the redesign of the user interface. It uses right click select by default. In 2.80 and newer left click select is the default. You right click to get special menu instead of pressing W. Shade smooth/Flat can be accessed through right click menu. Most of the menu options are still there but may be in different order. Most of the hotkeys are still the same. Like 75% I guess. Also layers have been replaces with collections, but you can still move object to new collections using M.
