Arrow keys move the tile cursor. The left and right square brackets rotate the garden a quarter turn. M switches between Build and Tend. Plus and minus zoom, and 0 fits the garden to the screen. In Build, keys 1 to 9 choose a piece, Enter or Space places it, and Delete removes one. In Tend, Q, W, E and R choose Rake, Ripple, Stone and Smooth, Enter or Space uses the tool, and holding Enter while pressing arrows rakes a straight line. T clears the sand, and Control or Command with Z undoes. With the cursor on the minifigure, P picks it up, the arrows carry it, Enter sets it down and Escape puts it back.
