We have had block select in Visual Studio for a long time. The idea of block select is simple, sometimes you want to select columns and rows (in a block) instead of the normal line by line select you get with normal drag-n-drop selection, or [SHIFT]+[ARROW] selection. We talked about this for older versions of studio on Trick number 002. Watch Trick number 503, to see what’s new in Studio 2010.
