问题 In current version of Mathematica these keyboard shortcuts are quite handy Ctrl+K completes current command GraphPl -> press Ctrl+K -> GraphPlot Ctrl+Shift+K completes current command and adds argument placeholders which could be replaced with actual values with tab key GraphPl -> press Ctrl+Shift+K -> GraphPlot[{vi1->vj1,vi2->vj2,...}] However I couldn't find any keyboard option to show associated settings/options For instance Say If I need to plot a graph with different layouts, I know I

问题 If I set the caret on a line and accidentally press Ctrl X or Ctrl C instead of Ctrl S , then the entire line is cut/copied, since there is no selection. This can be very annoying, and can often times destroy code in the clipboard which I wanted to paste. I'd expect nothing to happen if nothing is selected. How can this be turned off? 回答1: Go to Registry screen: Help | Find Action... and search for registry there Once there -- find and activate editor.skip.copy.and.cut.for.empty.selection

问题 is there any way to have either shortcut or icon for svn Update to HEAD of one project (not all of them) in eclipse? It would make my life much much easier. I have few php projects though.

You have to go to Settings > General > Keys and bind the shortcuts as the others have said. I have:

问题 I have a habit of hitting CTRL + T to open a new tab in ST2. However this invokes the transpose function. I could map the new_file command to CTRL + T , but is it possible to disable the command completely via user keymap file. My search suggested adding this to user keymap. [ { "keys": ["ctrl+t"], "command": "unbound" } ] Is the "unbound" an officially endorsed way of disabling a shortcut? 回答1: I have never see or read any official documentation about the unbound command, but it works.

问题 What is the keyboard short cut in Eclipse to jump to the closing brace of a scope? 回答1: Place the cursor next to an opening or closing brace and punch Ctrl + Shift + P to find the matching brace. If Eclipse can't find one you'll get a "No matching bracket found" message. edit: as mentioned by Romaintaz below, you can also get Eclipse to auto-select all of the code between two curly braces simply by double-clicking to the immediate right of a opening brace. 回答2: As the shortcut Ctrl + Shift +

问题 I want to open a file in Vim like in Eclipse using Ctrl + Shift + R , or via the Ctrl + N option of autofill. Invoke a keyboard shortcut, type the file name/pattern, and choose from all the matching files names. I know opening it normally like: :tabe <filepath> :new <filepath> :edit <filepath> The problem here is that I have to specify the whole file path in these cases. 回答1: I recently fell in love with fuzzyfinder.vim ... :-) :FuzzyFinderFile will let you open files by typing partial names

问题 Is there a way to use Nimbus LAF (Look And Feel) on OS X while still being able to use the Meta key for cut/copy/paste and select-all operations? I currently have the following code in my Swing app's main method, which changes up the LAF based on the operating system (default for OS X, Nimbus for all others): if (!System.getProperty("os.name", "").startsWith("Mac OS X")) { try { for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) { if ("Nimbus"

问题 I wanna setup a global hotkey in python 2.6 that listens to the keyboard shortcut ctrl + D or ctrl + alt + D on windows, please help me 回答1: Tim Golden's python/win32 site is a useful resource for win32 related programming in python.

Pyhk builds on pyhook. Hotkey registration is as simple as: pyhk.addHotkey

问题 Is it possible to have multiple actions assigned to one keyboard shortcut in visual studio code? For example: Move cursor up x 3 set to "ctrl + w" Thanks in advance. 回答1: Multiple actions is not supported natively (Feature-request: Macro like keybindings #871). Edit: macros doesn't seem to be working properly in the latest versions of vscode. There are other extensions though, like: multi-command "multiCommand.commands": [ { "command": "multiCommand.down3Lines", "sequence": [ "cursorDown",

问题 I'm working on some legacy code that has a class that is 10,000+ lines of code and has 100s of methods. Is there a shortcut for any JetBrains IDE (since the shortcut would likely be shared across all of them) to collapse all the methods / functions so that only the method signatures are shown? Something like this: public String myMethod(String arg1, int arg2){...} public String mySecondMethod(String arg1, int arg2){...} 回答1: You may take a look at intellij code folding shortcuts. For Windows
