right mouse click, defines a block from current cell to clicked cell

[michaelsjackson]

Defining a block between current cell position and right clicked mouse button. Imagine the emacs behaviour with the mouse, from point (current cell here) to right click, selecting a range. Same principle here. Simple, direct, powerful.

Instead of RMB twice, 2.57 introduces a combo where you click left and then right somewhere to select a region.

I hope that works for you.
