shortcut

问题 I have an app that allows you to create Home "shortcuts" to a specific Activity . It turns out that some of my users will use the app, hit the home key to go do something else, then use one of the shortcuts to jump back to that Activity. Since the app is still in memory it just opens the new Activity on top of the others and the "Back" key will take them back through the whole history. What I'd like to have happen is if they use a shortcut then to effectively kill the history and have the

问题 What is the keymap for navigating to the matching brace in IntelliJ IDEA? public void blah() {| ... } If | is my cursor, I would like to jump to the closing brace with this keymap. 回答1: I've only verified this with IntelliJ 9 but: On Windows: Ctrl + } will move to the close bracket. Ctrl + { will move to the open bracket. On Mac: Use cmd instead of Ctrl . 回答2: As an alternative to Ctrl + } and Ctrl + { you can by default use Ctrl + Alt + Shift + 9 and Ctrl + Alt + Shift + 8 respectively. I

问题 Please excuse my lack of better terminology. I have a string[] and I'd like to get the product of a catesian join with itself for later to put in a dictionary. However, I'd like all possible combinations except when there is a clone/duplicate key. string[] array1 = { "aa", "bb", "cc" }; string[][] arrayOfArrays = array1.SelectMany(left => array1, (left, right) => new string[] { left, right }).ToArray(); Will obtain a string[][] from all possible combinations yielding as each element: aa aa aa

问题 I have seen ways to make shortcuts, but I need to find a way to get a list of shortcuts installed on the phone. I want my user to be able to select one of his/her shortcuts and launch it from my application. Is there a way to do this (an API) or will I need a reflection method to call a system service? 回答1: The shortcuts are private to Launcher. There is no API, and anything you try to do will be very fragile as different launcher implementations (and versions) will have different storage

问题 The more options I have defined, the more a have to type when I have to modify them. So I'm looking for a shorter version of Properties.Settings.Default.varX I tried: Properties.Settings settings = Properties.Settings.Default; settings.var1 = "x"; settings.var2 = "y"; settings.var3 = "Z"; Properties.Settings.Default = settings; but Properties.Settings.Default is read-only and the Save function has no overload. So is there any other way than typing Properties.Settings.Default again and again?

问题 I'm using the Write-Host cmdlet to change the color of my prompt and I noticed that the DarkYellow color was not displaying as any sort of yellow, but as a gray!

问题 Is there any shortcut to collapse/expand the regions ONLY? Meaning, if I have a region with 5 methods in it, and I hit collapse, the region will collapse, and when I will hit expand, the region will expand and I will see all 5 methods with the same state as it was before (collapsed/expanded). Currently the shortcuts I found collapse ALL, or expand ALL, or substitutes the "All" word for the "Current" word. I'm looking for a shortcut that will collapse only regions, and will not do anything to

问题 Is there a "Find in Files" shortcut in Eclipse, as there is in Visual Studio ( Ctrl + Shift + F )? I have looked in these two lists: Eclipse Shortcuts "Show All Shortcuts" shortcut: Ctrl + Shift + L . Thanks. 回答1: select workspace and press Ctrl - H Which dialog is selected, depends on which file type is selected in the Project Explorer view. For example, if you selected a .js file and press Ctrl - H , it will bring up the dialog with the "Javascript Search" tab selected. If you want to

问题 Trying to make a keyboard shortcut to reset a game. Earlier in the __init__ class I create a menu to start a new game, and use self.reset to reset the score/grid etc. I now have been trying to implement the shortcut with the same command - the reset being a method within the class. self._master.bind_all('<Control-n>', self.reset) This is the error: TypeError: reset() takes 1 positional argument but 2 were given My confusion is that the self.reset works fine earlier in the __init__ but then

问题 I am working on a VBScript that is to show the "Computer" icon on the desktop. I've been able to do one for IE using the following code, however as Computer is a "Special Folder" that does not seem to have an actual location I can't use the same method. Would anyone have any idea how to enable it via VBScript?
