Hi, people! :D
Lately, I've received several emails asking for this tutorial, and also, as some changes have been made in Blender during the last months, I decided to make a clear explanation in all the techniques I know for navigating through the 3D scene. Blender puts at our disposal a lot of tools for navigating in the scene, position cameras, flying around, interacting with objects... From options in the User preferences, to hotkeys, a lot of things have impact on how we navigate.
I hope you've understood everything shown in this tutorial, and if you aren't new to Blender, maybe you learned a few little tricks ;)
