We have some enormous Grids with lots of Columns (they work surprisingly fast in operations mode). But its always tediously slow to shift the sequence of a column in the grid clicking the Up and Down links.

I just slipped on my keyboard and held down the spacebar after clicking Up and found it moved a row UP continuously. Holding down the spacebar makes moving rows (columns) super fast. Same thing applies if you click Down then hold the spacebar.
The benefits of greasy fast food close to your keyboard continues to impress me.
