问题 In my application I have a JTable where I mapped a Key event. The source: getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT).put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0), "selectNextColumnCell"); getActionMap().put("selectNextColumnCell", new AbstractAction() { @Override public void actionPerformed(ActionEvent e) { //DO SOMETHING } }); } But this action is only called when I press the enter key and don't release it.

问题 In shell mode on emacs, the current key binding for quitting the shell mode ( 'comint-interrupt-subjob ) is "\C-c \C-c" , and I want to change it to "\C-c" as in ordinary linux shell.

问题 I have a .sql file that I am editing in Emacs 24, and I am looking for a way to comment out a selection or a line.

Perhaps there is something that I can add to my .emacs to enable such a keybinding? (I am a bit of a novice to Emacs) Thanks. EDIT After a little exploring, I found M-x comment-region to do the trick for single line comments.

问题 To help me learn to work with various emacs modes, I would like to have a second monitor with a little HTML page that is used for showing me what sorts of things I can type or key-chord on whatever I'm currently looking at in emacs. So how can I get a list of all the commands or key-chords available to me in my current mode? 回答1: Someone else will no doubt tell you how to get a cheatsheet such as you request (well, here is info about that too). But if you want something that tells you

问题 This is a pong game I made, but the only thing that is not working is the paddles moving. I am not sure how to make the keyboard work with the program.

问题 So, I made a method that you can pass 2 AbstractAction to, the first one performs the key pressed event and the second performs the key released event. When the I press and release the UP key both actions get fired off, that is fine. If I press and hold the UP key both actions are still fired off. Why are both being fired?
