Physics Activity

Today I have found out that you can browse Sugar using keys instead of mouse only.
F1 = Takes you to neighborhood.
F2 = Takes you to group.
F3 = Takes you back to home.
Alt+Tab = Allows you to switch from activity to another.
I'm really enjoying the activity physic as it is fun to play around with blocks.
You can create blocks and it drops like real building blocks. Young children will enjoy this as they can build houses.
The functions on the activity physic are:

-Play/pause
-Draw
-Triangle
-Polygon
-Erase
-Motor
-Box
-Grab
-Pin
-Circle
-Joint

There are more other activities that are entertaining as well but I think Physic is one of the best out off all activities.
