Open a type (e.g.: a class, an interface) without clicking through interminable list of packages: Ctrl + Shift + T

Go directly to a member (method, variable) of a huge class file, especially when a lot of methods are named similarly: Ctrl + O

Go to line number N in the source file: Ctrl + L, enter line number.

Go to other open editors: Ctrl + E.

Move to one problem (i.e.: error, warning) to the next (or previous) in a file: Ctrl + . for next, and Ctrl + ,
