If there was one thing that was going preety steadily on my nerves in VS2005 was region collapsing/opening with mouse.
So i was determined to find a shortcut for it.
And I found so much more...
Every shortcut there is in Visual Studio 2005 is listed here.
All SSMS keybard shortcuts are listed here.
These two pages are the holy grail of fast development if you ask me :))
oh and by the way.... collapsing/opening a region is CTRL + M + M. Yes, hit M twice while holding CTRL.
And do try CTRL + I... it's pure pleasure. a hint: Incremental Search :) <-- select text (works in VS and SSMS)
