List all Keybindings for a certain emacs mode

阅读更多关于 List all Keybindings for a certain emacs mode

I know that I can list all the keybidings avaliable in emacs by using C-h b, but is it possible to list only the keybindings that apply to a certain mode, say dired-mode. In dired+, I can do ? h and it shows me all the applicable dired mode keybindings. Thanks use C-h m or M-x describe-mode Not sure what the question is. C-h b shows you all of the key bindings currently available (i.e., in the current mode). If you want to see only the key bindings provided by a mode's own keymap, then use library help-fns+.el and hit C-h M-k . You are prompted for the keymap variable (e.g. dired-mode-map ).

How to capture Ctrl + Tab and Ctrl + Shift + Tab in WPF?

阅读更多关于 How to capture Ctrl + Tab and Ctrl + Shift + Tab in WPF?

What would be some sample code that will trap the Ctrl + Tab and Ctrl + Shift + Tab for a WPF application? We have created KeyDown events and also tried adding command bindings with input gestures, but we were never able to trap these two shortcuts. Szymon Rozga What KeyDown handler did you have? The code below works for me. The one that gives me trouble is: Alt + Tab , but you didn't ask for that :D public Window1() { InitializeComponent(); AddHandler(Keyboard.KeyDownEvent, (KeyEventHandler)HandleKeyDownEvent); } private void HandleKeyDownEvent(object sender, KeyEventArgs e) { if (e.Key ==

Detect if a key is bound to something in vim

阅读更多关于 Detect if a key is bound to something in vim

I'd like to know if there is a way to figure out if a key does something in vim. I know that I can use :map to see user-defined mappings, but is there something for the built-in stuff? For example, I always had CTRL - W bound to close tab, because I thought that it was unused. After half a year, I found out that there are some sequences that use it, like CTRL - W CTRL - S to split the window, and it was a nightmare to retrain myself. If you check out the suggested answer by Randy Morris you will find that :help index will give you the list you want. To check the default mapping: :help index

Emacs: print key binding for a command or list all key bindings

阅读更多关于 Emacs: print key binding for a command or list all key bindings

问题 In Emacs (GNU 23.2, *nix), how can I: list the key sequences bound to a particular command? For example, how can we list all the key sequences that execute save-buffers-kill-emacs , with the output of key sequences bound to it? Assuming we can do this, listing the key sequences bound to goto-line should print the output: M-g g on a default install. list all key-bindings? Does C-h b do this? Would it print my own bindings? I am aware that executing the command directly can print a key sequence

Program not painting screen properly

阅读更多关于 Program not painting screen properly

问题 I've been constructing a short program that basically draws a spaceship on a JPanel and listens for keys that tell the program to shoot a bullet. The problem is that it's not even painting the spaceship or the bullets on the screen. I also suspect that the KeyBindings may not be working as that was a previous problem (that I may or may not have fixed), but the main issue at hand is still the fact that my screen isn't being painted. Here is my code: public enum Direction { LEFT, RIGHT, SPACE }

Detecting Key Presses using win32api in Python

阅读更多关于 Detecting Key Presses using win32api in Python

I'm trying to break a loop in Python with a specific key press using win32api. How would one go about this? What is the actual version of win32api.KeyPress('H') , in the following code? Revised: import win32api while True : cp = win32api.GetCursorPos() print cp if win32api.KeyPress('H') == True : break I want to be able to break a loop by pressing the h key. Edit: I'm attempting to make a program that repeatedly reports mouse positions and I need a mechanism to exit said program. See revised code. win32api is just an interface to the underlying windows low-level library. See the

JTable Key Bindings

阅读更多关于 JTable Key Bindings

问题 I want to trigger an save action anywhere in my application (Control+S). I've added the necessary key binding, and the action triggers as expected. However, if I try Control+S on a JTable the table starts my custom action and activates the table cell for editing. I think I've disabled the edit action in the table's input map. What am I missing here? import java.awt.Dimension; import java.awt.event.ActionEvent; import javax.swing.AbstractAction; import javax.swing.ActionMap; import javax.swing

问题 Background My window is a java.awt.Frame, and inside of the Frame are two Panels (java.awt.Panel). I'm trying to make it so that the window handles buttons I press.
