Some people like shortcuts, some people prefer using menus and the mouse. For the people that like using the shortcuts, Lightroom is full of it. The last I checked, the Adobe techie where at 300+ shortcuts. Every shortcut can be executed via the menus or some context menu. Here are the shortcuts that I use on regular basis, pretty much every time I use Lightroom.
