The list of available key bindings in Eclipse depends on many factors, including
what view or editor is selected, whether a dialog is open, what plug-ins are
installed, and what operating and windowing system is being used.  At any
time, you can obtain a list of available key bindings using Key Assist 
( Help > Key Assist...
or Ctrl+Shift+L).  The following tables list some 
popular key bindings available in the Java development tools.
