Unfortunately, the optimization patch broke my PDT, DBViewer and Wireframesketcher. WS is not available in preferences any longer so I can't report a bug this way. I'll get back to you after I restore my Eclipse.
I installed the patch from here:
http://download.eclipse.org/eclipse/updates/junoSR1Patch-tmp
It appears that the keyboard shortcut issue is Juno related. CTRL+D works and is visible in my Zend Eclipse for PHP Developers installation based on Eclipse 3.7.2.
