after reading About Productivity from Roy I couldn't agree more.
I always love to learn from people around me,
I have two guys on my team, Lior - who masters all vs ( from 6.0 to 2003) shortcuts
and Saar Carmi who loves to make "Saturday Components" - he made a Collapse Tree addin for VS , when I press ALT+T+T, I get the Visual studio tree to collapse, I hit it all the time ;)
I asked him to make a public release of it, it's a must
And a Tip: if u press CTRL+SHIFT+I on Visual Studio .net you could do a search while you type , once you found what you're looking for you could press F3 to find the same string again.
