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.

	 * 
	 * @param activeBindings
	 *            This is a map of triggers ( <code>TriggerSequence</code>)
	 *            to command ids (<code>String</code>). This value will only
	 *            be <code>null</code> if the active bindings have not yet
	 *            been computed. Otherwise, this value may be empty.
	 * @param activeBindingsByCommandId
	 *            This is a map of command ids (<code>String</code>) to
	 *            triggers ( <code>TriggerSequence</code>). This value will
	 *            only be <code>null</code> if the active bindings have not
	 *            yet been computed. Otherwise, this value may be empty.
	 * @param prefixTable
	 *            A map of prefixes (<code>TriggerSequence</code>) to a map
	 *            of available completions (possibly <code>null</code>, which
	 *            means there is an exact match). The available completions is a
	 *            map of trigger (<code>TriggerSequence</code>) to command
	 *            identifier (<code>String</code>). This value may be
	 *            <code>null</code> if there is no existing solution.
