I'm using the shortcuts to expand / minimize methods quite a lot. For some reason all of these have suddenly (after starting Eclipse this morning) stopped working, and I'm a bit dumbfounded as to why. All other shortcuts (at least that I know of, and have tested) work just fine.
I've attempted to restart Eclipse and checked the error logs (nothing there).
Running latest (stable, not RC) Eclipse Juno on Ubuntu 12.04.
