Vi keybindings for R command line like in Bash

老子叫甜甜 提交于 2019-12-03 15:48:28
问题 Context I like editing and manipulating the bash command line using vi-style key bindings with the following setting: set -o vi However, when I start R on the command-line, these keybindings disappear. I know that the Vim-R plugin allows for Vim keybindings when you run R through the Conque Shell, but I'm not entirely happy with that experience, and, regardless, sometimes I just want to run R on the standard command-line. Question Is there any way of getting Vi style key bindings in R on the

Renaming Objects in RStudio context sensitive within entire Project

柔情痞子 提交于 2019-12-03 14:40:57
问题 I have an issue when developing an R project using RStudio. I create an object, and then realise later, that I want to give it another name. I then have to manually change the name, which in larger projects is annoying and often results in errors, as I easily oversee one line. The replace all function of RStudio doesn't quite match the name I am trying to replace, as it only does so in one file, it also doesn't consider only the references of the variable see sample code: f <- function(a){ b

How to create keyboard shortcut in windows that call function in my app?

折月煮酒 提交于 2019-12-03 14:28:01
How can I create an application that performs an action with keyboard shortcut (App must be unvisible). For example Shows MessageBox when user press Ctrl + Alt + W . Chris Taylor One solution would be to use interop and use the Win32 RegisterHotKey API. Here is a quick and dirty example I just put together so it is not well tested and I am not sure that there are no unexepcted side effects, but it should work. First here is a simple HotKeyManager this takes care of the basic interop, provides a hidden window to handle the native Windows messages (WM_HOTKEY) which is translated into a .NET

Eclipse shortcut “debug last debug configuration” (not F11)

断了今生、忘了曾经 提交于 2019-12-03 14:25:43
问题 I'm looking for a shortcut to debug the last debug configuration. I know about the existence of F11 , but the problem is, that I want to start debugging the last configuration. F11 runs the debugging of the class currently opened. I thought it would be easy to find that shortcut on the net, but no luck... 回答1: Check the prefs, namely "Run/Debug" -> "Launching" -> "Launch Operation". There you can select what F11 does: Run/Debug the file open in the current editor or use the last launch config

How to register a custom keyboard shortcut for a windows application

孤街醉人 提交于 2019-12-03 14:14:34
I want to create a windows utility application, which can be called anytime from within any other application using a keyboard shortcut, e.g.: • Win + T • Ctrl + T • Alt + T • Ctrl + Alt + T • Ctrl + Shift + T What key combinations can I use and how to setup those in the windows registry? (If the shortcut is used by an other application, it should of course not work.) Amr Elgarhy An option for doing that programatically when your application start is calling this Windows API: RegisterHotKey(IntPtr hwnd, int id, int fsModifiers, int vk); And to unregister call this API: UnregisterHotKey(IntPtr

Doing key combos with jQuery / JavaScript

我怕爱的太早我们不能终老 提交于 2019-12-03 13:33:17
I'm curious how i, with the following jQuery plugin code im writing at the bottom of this question, could implement key combos. How it's working so far is it allows a user to create key commands simply by doing a normal jQuery like syntax and provide an event for the key command, like so: $(window).jkey('a',function(){ alert('you pressed the a key!'); }); or $(window).jkey('b c d',function(){ alert('you pressed either the b, c, or d key!'); }); and lastly what i want is the ability to do, but can't figure out: $(window).jkey('alt+n',function(){ alert('you pressed alt+n!'); }); I know how to do

How can I quickly create Javadoc links to elements in Eclipse?

删除回忆录丶 提交于 2019-12-03 13:02:45
I want to easily create links to classes, methods, fields, etc. from within my Javadocs without having to type out the full expression e.g., {@link AllowAllHostnameVerifier} . What is the fastest way to do this in Eclipse? Jeff Axelrod If you don't already have a Javadoc for the element you're documenting, press Shift + Alt + J . Using the AllowAllHostnameVerifier example, from within the Javadoc comment where you'd like the link, use autocomplete: Type AAHV then Ctrl + Space . Select {@link AllowAllHostnameVerifier} from the list of autocomplete options by pressing ↓ then Enter . As an

How to assign a shortcut key (something like Ctrl+F) to a text box in Windows Forms?

人走茶凉 提交于 2019-12-03 12:50:37
I am building a tool using C#. It's a Windows application. I have one text box on a form, and I want to assign focus to that text box when the user presses Ctrl + F or Ctrl + S . How do I do this? Capture the KeyDown event and place an if statement in it to check what keys were pressed. private void form_KeyDown(object sender, KeyEventArgs e) { if ((e.Control && e.KeyCode == Keys.F) || (e.Control && e.KeyCode == Keys.S)) { txtSearch.Focus(); } } Aseem Gautam One way is to override the ProcessCMDKey event. protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { if (keyData ==

Method of quickly changing between view and controller in visual studio - ASP.NET MVC

自作多情 提交于 2019-12-03 12:02:51
问题 Is there a way of quickly switching between controllers and views in Visual Studio when developing ASP.NET MVC applications? I find that the solution explorer has quickly become very difficult to navigate through simply due to the quantity of files that is in there. 回答1: Answering my own question Yes there is. There appears to be a default shortcut key Ctrl - M then Ctrl - G . This will automatically switch between the two. If you're on the controller/action it will switch to the view and
