One of the great additions in Visual Studio 2005 are SmartTags.  These are the little drop down menus that appear in the IDE when you’re writing code.  The one I use the most is ‘Add Using’ functionality.  What I don’t like about SmartTags is the default key stroke (Ctrl+Alt+F10) that ships with Visual Studio 2005.  Who can feel comfortable with this monstrosity of finger yoga?  The first thing that I do when I start working with a fresh IDE is to remap the View.SmartTagShow View.ShowSmartTag item to Ctrl+Alt+Down Arrow.  I find that it is more intuitive (you are, after all, trying to make something appear in a downward fashion) and much more physically comfortable.
