Is it possible to nagivate Blender viewport like with WASD in a video game? In video games, flying in the level is typically like this:


W - move forward;
S - move backward;
A,D - move right/left without turning;
Space - jump/ascend;


If I try this in Blender, it does not work (and in general makes some mysterious hard-to-undo changes when I press unknown keys).


Is there any easy mode for navigating the scene using video-game-like controls?
Is there even mode video-gamish mode with gravity (towards the center of the closest big object) and clipping (not allowing point of view to become too close to some surfase)?
The shortcut is now Shift-`, for `2.79` use Shift-F. Then you can use WSAD.
