Ctrl+N Go to Type
Ctrl+Shift+N Go to File
Ctrl+F12 Go to Member

It's like instant teleportation all over the solution. No mouse. No struggling with the Solution Explorer. Example:
Ctrl+N, type FAM, all classes matching the pascal casing with (F)xx(A)xx(M)xx will be displayed, like FormsAuthManager. Select one with keyboard to navigate to the file. Once there, Ctrl+F12, type VU for ValidateUser and enter to navigate to method, etc.

Try out the StudioTools plugin I linked to above and see what you think. Default is alt+o to open any file, and ctrl-g to go to any type.
