The result is : If ABCDEF is a hexagon with opposite sides parallel (not necessarily equal), then the respective centroids G, H, I, J, K and L of triangles ABC, BCD, CDE, DEF, EFA and FAB, form a hexagon with opposite sides both equal and parallel.

To place the least burden of new-ness on these users while still decreasing the number of button presses, we now consider schemes where the only alteration of the keyboard is the ...
