On Finding The Anykey
Finally I’ve found it: The mysterious “Anykey” is living under the strange name of “QuickFix” in your IDE of choice.

Pressing Alt+Enter (Cmd+Enter) in Intellij IDEA or Ctrl+1 in Eclipse enables you to program on a “per example” basis. You can do
introduction of variables, fields, classes,
renaming
changing method signatures
completing structure
surrounding code with live template
importing dependencies
and much more …

and much more just by pressing the “AnyKey” at any offending piece of code. Especially the ton (600+) of intentions of IDEA fixes almost each possible syntax problem using a single key.
Kent Beck used the AnyKey (QuickFix) when describing the Refactoring By Example.
You can find further keystroke reference cards in the help menus of your IDE.
DZone made up a nice collection of refcardz:
IntelliJ IDEA DZone Refcard
NetBeans 6.1 Refcard
