问题 The WPF Treeview responds to + and - keystrokes to expand and collapse nodes in the tree. Great! Is there an existing command I can bind my toolbar buttons or menu items to to perform the same actions in the treeview?

问题 In Eclipse, in the menu, I can go to Window -> Preferences -> Keys and set the Scheme to "Emacs."

The File -> Import option seems to neither support .CSV files or a specific keyboard configuration file. 回答1: You could try exporting and importing all of your preferences Export

问题 In Delphi 7's TMemo control, an attempt to do the key combo Ctrl + A to select all does not do anything (doesn't select all). So I've made this procedure: procedure TForm1.Memo1KeyDown(Sender: TObject; var Key: Word; Shift: TShiftState); var C: String; begin if ssCtrl in Shift then begin C:= LowerCase(Char(Key)); if C = 'a' then begin Memo1.SelectAll; end; end; end; Is there a trick so that I don't have to do this procedure? And if not, then does this procedure look OK? 回答1: This is more

问题 Due to automatic code completion, I regularly find myself in between parentheses, having to get to the end of a line to add the inevitable semicolon. Then I have to get my right hand up, move it to the right, hit End , and come back to the main part of the keyboard again to enter the semicolon. I perceive this as disturbing to my flow of typing, especially when writing on a notebook, as then those moves of my hand are very inefficient. Is there already a key combination for reaching the end

问题 Is there a keyboard shortcut that allows you to easily change Build Configuration (say, from Debug to Release) in Visual Studio (2008)?

The Build.SolutionConfigurations command will put your

问题 Emacs seems to have all the possible keyboard combinations already randomly distributed among it's commands. :p If I am to define new keyboard shortcuts, where should I put them? Which prefixes should I use? For instance: I want to define shortcuts for the following functions: indent-buffer (C-c i, after I got the answer) comment-or-uncomment-region (C-c C) rdebug (ruby debugger) (C-c R) rsense-complete (ruby autocomplete) (C-c e) Where would you put these? Why? 回答1: Emacs actually has a very

问题 The same question has been asked for Xcode 3 But the solution there is said to not work with Xcode4. And no new solution is available there. How to get a key-binding to move the curser up/down about 10 lines in Xcode 4 ? 回答1: Eureka!

Add a new dictionary

问题 Is there a default key binding in VSCode to wrap a selection in an HTML tag like the keyboard shortcut Shift+alt+W in Visual studio 2015?

问题 I've got a simple Qt app, and I just want to respond to the F12 key, regardless of which widget has focus. Is there some easy signal or something I can hook in to? I want to use the F12 key to toggle the main window fullscreen on/off. 回答1: I haven't tried, but here is what I would do : Create a QShortcut and make sure its context (with setContext() ) is Qt::ApplicationShortcut . shortcut = new QShortcut(QKeySequence(Qt::Key_F12), parent); shortcut->setContext(Qt::ApplicationShortcut); Then
