key-bindings

For whatever reason, the KeyBindings for my UserControl aren't working as soon as my WPF Application loads. They do work after I press a button on the form but not when I set focus to the form by clicking or alt tabbing or moving or anything like that. And when they do work my enter keys print a random number. (sometimes 5, sometimes 7 etc...). <UserControl x:Class="WpfCalculator.View.CalculatorView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300" > <UserControl.InputBindings> <KeyBinding Key=

I am trying to make key bindings in Java on a JPanel. I want a certain action to execute when I press the 'w' button. I follow the Java tutorial on making bindings, but the actionPerformed method does not execute (i.e. no text prints out). The following is the entirety of the code for my test GUI, with the relevant part highlighted: import java.awt.BorderLayout; import java.awt.event.ActionEvent; import javax.swing.AbstractAction; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.KeyStroke; @SuppressWarnings("serial") public class Test extends JFrame{ private JPanel

I have just created a java tic-tac-toe game i would like to figure out how to run a method once the enter key is pressed during a certain condition an example is below... if(/*condition is met*/){ //keyListener } Depending on where you want to trap the "enter" key, you could use an ActionListener (on such components such as text components or buttons) or attach a key binding to you component public class MyPanel extends JPanel { public MyPanel() { InputMap im = getInputMap(WHEN_FOCUSED); ActionMap am = getActionMap(); im.put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0), "onEnter"); am.put(

I'd like to bind Ctrl + R to 'isearch-backward and bind Ctrl + Shift + R to 'tags-apropos but I can't distinguish between the two key presses. Can emacs differentiate between Ctrl + R and Ctrl + Shift + R ? What should go into my .emacs file to allow this keybinding? Yes. (global-set-key (kbd "C-r") 'isearch-backward) (global-set-key (kbd "C-S-r") 'tags-apropos) The way to figure out the answer to this kind of question is to do help on a key C-h k , and type the keystrokes you're interested in. What Emacs shows in the Help buffer is the string you can pass to the macro 'kbd . Yes -- one is "\C

I am writing an elisp function that permanently binds a given key to a given command in the current major mode's keymap. For example, (define-key python-mode-map [C-f1] 'python-describe-symbol) The command and the key sequence are gathered interactively from the user. However, I am having trouble producing the name of the KEYMAP (e.g. 'python-mode-map') that corresponds to the current major mode. I have tried the function (current-local-map), but this function returns the keymap object itself, rather than its name. I understand that many major mode keymaps are named according to the convention

I've read this , but my question is different. I'd like to know how to view key-bindings in Emacs which start with a particular key. I'd like to bind f2 , but would like to know what it's currently bound to. Pressing C-h m prompts for the key sequence. Entering f2 here results in Emacs waiting for me to complete the chain, as f2 alone does nothing. How can I view all key-bindings which start with f2 ? F2 F1 or F2 C-h In general, typing F1 or C-h after any prefix-binding will list all the bindings using that prefix: describe-prefix-bindings is an interactive compiled Lisp function in help.el .
