In Eclipse, pressing ctrl-shift-l (l as in lima) will show you available shortcut keybindings in the current context. Sweet. 🙂 Found through this post over at Cedric Otakus blog.
Update: Doesn’t really seem to work does it? 😉 I’m suspecting Cedric has emacs bindings on. Check out http://eclipse-tools.sourceforge.net/Keyboard_shortcuts_(3.0).pdf for a reference sheet of the default keybindings.
