Looking For Grab Grid option in Blender 2.57b


I am working on an animation and would like to ensure that the feet of my model moves in fixed distances, in 2.3x one had to activate the Grab Grid option in the User Preferences Window under the View and Controls buttons.

Can anybody help me locate this option? I tried searching for it (space bar) but cannot find it. Perhaps the name has changed.

Many thanks…

On the botom of the 3D-View is a little Magnet-Icon. Press it and Snapping is enabled.
You can setup the size of the grid in the Properties-Window under the Display tab.

Thanks 0BackBONE0!
