key-bindings

问题 This question already has an answer here : Why the key binding M-S-t fails while C-S-t works? (1 answer) Closed last year . By default, C-S-t and M-S-t are both unbound in my Emacs. Hence, when I press them, they are translated into C-t and M-t . Fine, but I want to use them for a tweak on the original function, and therefore put these lines in my .emacs : (global-set-key (kbd "C-S-t") 'transpose-chars-backward) (global-set-key (kbd "M-S-t") 'transpose-words-backward) The functions there are

问题 Is there a way to make simultaneous key presses into a keybinding, e.g. for the keys w , e , f , when pressed within 0.05 seconds of each other, to trigger a command? To be more specific: If w , e , f are pressed within 0.05 seconds of each other, then upon the pressing of the last one, XMonad should trigger said command. XMonad should also have intercepted the three keys so that they are not superfluously sent to the focused window. Otherwise (if at least one of them are not pressed within

问题 How would I go about setting up a keybinding so when I press for example Ctrl + Shift + T in eclipse it surrounds the selected lines with a time measurer. Like so: 1: CODE CODE CODE 2: Select three lines and press CTRL+SHIFT+T 3: long startTime = System.currentTimeMillis(); CODE CODE CODE Print.pln("Time taken: " + (System.currentTimeMillis() - startTime) + "ms"); 回答1: You can achieve this by using a template, for example: long ${newName} = System.currentTimeMillis(); ${line_selection} Print

问题 In my form, when i press ENTER button in my keyboard, the okAction() method should be invoke (and invoke perfectly). My problem is in focus state, When i fill the text fields and then press the ENTER button, the okAction() didn't invoked, because the focus is on the second text field (not on the panel). How fix this problem? public class T3 extends JFrame implements ActionListener { JButton cancelBtn, okBtn; JLabel fNameLbl, lNameLbl, tempBtn; JTextField fNameTf, lNameTf; public T3() { add

问题 I read that it is better to use KeyBindings than KeyListeners. I see how KeyBindings are useful for a specific reaction to a specific key; but I am also trying to detect the press/release of ANY key on the keyboard: is there a way to do this with KeyBindings? For example, I would use KeyBindings normally to act on a single key as so: InputMap iMap = component.getInputMap(); ActionMap aMap = component.getActionMap(); iMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0), "enter without

问题 (Note: I am aware of this question in which the user would have to enter a Terminal command to fix this issue, but I would prefer a solution in which the solution can be put into the application.) To explain, I am using KeyBindings in a Java application; however, if one holds a key like a, e, i, o, u, n, s, etc., the diacritic menu OSX uses somehow completely disables key input. It does not, however, affect mouse input if that is relevant. Here is some sample code in which the problem can be

问题 I am very new with emacs and Lisp, though from experience with other functional languages it's not too hard for me to mimic what I am seeing in useful code snippets. I've added some nice window toggling features in the .emacs file and they are working well. But on start-up, I'd like to configure a specific arrangement of windows/frames. Basically, I want to do the following each time I launch emacs (which is generally at most once per day and then it is left open for days/weeks). 1. Split the

问题 My window has just a listview. This facilitates the users to incremental search the db. Since the design does not have a textbox, i've to globally handle the keys. I think it could be achieved by keybinding. But how can i handle all the keys and associate it to a single command. Also suggest me other methods if any. P.S.: I want this in xaml 回答1: I would use an EventToCommand binding the KeyDown event to a command on the ViewModel. You can set PassEventArgsToCommand to true, and use a

问题 How can I disable JTable's default behaviour of returning to the first row, when tab key is pressed in the last cell of the table? Instead the current cell should keep its focus. 回答1: The short answer: find the action that's bound to the Tab, wrap it into a custom action that delegates to the original only if not in the last cell and replace the original action with your custom implemenation. In code: KeyStroke keyStroke = KeyStroke.getKeyStroke("TAB"); Object actionKey = table.getInputMap

问题 With jedi-mode enabled, the C-tab is bound to jedi:complete . How can I unbind it so that I can then bind it back to other-window ? I've tried: (global-set-key (kbd "C-`") 'jedi:complete) (global-set-key [C-tab] 'other-window) (global-unset-key (kbd "<C-tab>")) (defcustom jedi:key-complete (kbd "C-`") "Keybind for command `jedi:complete'." :group 'jedi) None of them is getting me the desired results. 回答1: You can use: (define-key jedi-mode-map (kbd "<C-tab>") nil) None of the commands with
