In Eclipse I was able to register a set of classes for static import auto-completion, e.g. Math., Assert., EasyMock.*
With this enabled I was able to hit ct
Just do the reference once, then put the caret on the class name (ie Math), press alt+enter and choose "add on demand static import for 'java.lang.Math'. Intellij will add
import static java.lang.Math.*;
to the top of the file.
