Build: Blender 2.56a SVN r34736 Win32
Confirmed with other users on irc#blender
Standard sculpt keys have not been implemented as per documentation.
Toggle Airbrush (A) exhibits strange behaviour ... resets stroke mode to <empty/null> instead of returning to previous stroke mode. Random behaviour when starting from other modes.
Toggle Add/Subtract (V) is toggling to/from Vertex Paint mode.
Draw (D) non-functional
Grab (G) not-functional
...
Other default hotkeys are non-functional (see
http://wiki.blender.org/index.php/Doc:Manual/Modeling/Meshes/Sculpting for full list of hotkeys).
...
Constraints (X/Y) non-functional
Contraint (Z) functional but switches to wireframe (not overly helpful in sculpt mode).
I apologize in advance if this is already on the TODO's or other bug reports, I tried my best to find any mention of it, it did track down a video on custom hotkeys, however the standard ones don't appear to be set and the brush panel has changes significantly since.

Kindest regards.
