Bug 86184 [KeyBinding] registry: Missing key binding for paste in emacs scheme
3.1 M5a 1. start fresh workspace 2. Window > Preferences > General > Keys 3. switch to "Modify" 4. select emacs scheme 5. select "Edit" category 6. select "Paste" command ==> all key bindings are missing, only the binding provided by "Editing Text" is there. This might be caused by the fact that Ctrl+Y is already declared in org.eclipse.ui/plugin.xml for the redo command.

/**
 * <p>
 * A central repository for bindings -- both in the defined and undefined
 * states. Schemes and bindings can be created and retrieved using this manager.
 * It is possible to listen to changes in the collection of schemes and bindings
 * by attaching a listener to the manager.
 * </p>
 * <p>
 * The binding manager is very sensitive to performance. Misusing the manager
 * can render an application unenjoyable to use. As such, each of the public
 * methods states the current run-time performance. In future releases, it is
 * guaranteed that that method will run in at least the stated time constraint --
 * though it might get faster. Where possible, we have also tried to be memory
 * efficient.
 * </p>
 * <p>
 * <em>EXPERIMENTAL</em>. The commands architecture is currently under
 * development for Eclipse 3.1. This class -- its existence, its name and its
 * methods -- are in flux. Do not use this class yet.
 * </p>
 * 
 * @since 3.1
