The keyboard shortcuts in the SL Wiki have been updated to show shortcuts for version 3.2. This is the one with the new user interface. You could memorize them and remove all the buttons from your viewer setup. Not something I would do. But, there are some handy shortcuts. I’ll explain some of the ones I like.
The wiki page: All Second Life keyboard shortcut keys.
For User Interface (UI) developers there is a special page for working out shortcut keys based on operating systems. See: Shortcuts SL-UX.
