這兩天在配置一個CNF導航視圖時候發現快捷鍵delete、past、copy等都失效了，折騰良久，搞清楚了；

1.快捷鍵要想能在菜單右邊顯示出來：

deleteAction.setActionDefinitionId(IWorkbenchCommandConstants.EDIT_DELETE);2.要想生效必須綁定handler：
@Override	public void fillActionBars(final IActionBars actionBars) {		if (textActionHandler == null) {			textActionHandler = new TextActionHandler(actionBars); // hook																	// handlers		}		textActionHandler.setCopyAction(copyAction);		textActionHandler.setPasteAction(pasteAction);		textActionHandler.setDeleteAction(deleteAction);		// renameAction.setTextActionHandler(textActionHandler);		updateActionBars();		textActionHandler.updateActionBars();	}
public void updateActionBars() {		actionBars.setGlobalActionHandler(ActionFactory.CUT.getId(),                textCutAction);		actionBars.setGlobalActionHandler(ActionFactory.COPY.getId(),                textCopyAction);actionBars.setGlobalActionHandler(ActionFactory.PASTE.getId(),                textPasteAction);		actionBars.setGlobalActionHandler(ActionFactory.SELECT_ALL.getId(),                textSelectAllAction);		actionBars.setGlobalActionHandler(ActionFactory.DELETE.getId(),                textDeleteAction);	}setGlobalActionHandler把id和action綁定到一塊；
這里你發現綁定的action并不是自己那個action，是texthandler中的action；
如果想強制生效可以直接把這個action換成我們那個action；
3.推薦的解決方法：
之所以不生效，是因為系統找不到action對應的commandid，我們可以綁定：
PRotected void makeActions() {		clipboard = new Clipboard(shell.getDisplay());		...		deleteAction.setActionDefinitionId(IWorkbenchCommandConstants.EDIT_DELETE);		initActionCommandMappingService();	}	/**	 * 快捷鍵綁定actionBars.setGlobalActionHandler();	 * 這里使用了textActionHandler.updateActionBars();所以綁定的是textActionHandler中text*Action，而不是這里的action；	 * 方法一：重新設置setGlobalActionHandler為這里的action；	 * 方法二：ActionCommandMappingService中添加這里的action映射WorkbenchCommandConstants.EDIT_*	 */	private void initActionCommandMappingService() {		final IActionCommandMappingService actionCommandMappingService = (IActionCommandMappingService) CommonUIPlugin.getDefault().getWorkbench()				.getActiveWorkbenchWindow().getService(IActionCommandMappingService.class);		final String idDelete = actionCommandMappingService.getCommandId(ActionFactory.DELETE.getId());		if (idDelete == null) {			actionCommandMappingService.map(ActionFactory.DELETE.getId(), IWorkbenchCommandConstants.EDIT_DELETE);		}		final String idCopy = actionCommandMappingService.getCommandId(ActionFactory.COPY.getId());		if (idCopy == null) {			actionCommandMappingService.map(ActionFactory.COPY.getId(), IWorkbenchCommandConstants.EDIT_COPY);		}		final String idPast = actionCommandMappingService.getCommandId(ActionFactory.PASTE.getId());		if (idPast == null) {			actionCommandMappingService.map(ActionFactory.PASTE.getId(), IWorkbenchCommandConstants.EDIT_PASTE);		}	}這樣問題就解決了
