Camelback shortcuts: Let's say you have a class named DealCommitmentTypeBuilder. Sure, you can type the beginning and then do ctrl-space or ctrl-shift-space to get the name to pop up.
But did you know you can just type DCTB and ctrl-(shift)-space? Just type the capital letters.
Bonus tip: this works in the Ctrl-N and Ctrl-Shift-N windows as well.
