jQuery already handles that. To check if control was pressed you should use: $(window).keydown(function (e){ if (e.ctrlKey) alert(“control”); }); The list of modifier keys: e.ctrlKey e.altKey e.shiftKey And as fudgey suggested: e.metaKey Might work on MAC. Some other ways here as well.
You should use tabIndex attribute to be able to listen onKeyDown event on a div in React. Setting tabIndex=”0″ should fire your handler.
The answer in the proposed duplicate is incorrect, unfortunately. It doesn’t ignore repeated KeyDown events, and so will gradually increase the “delta” value in the direction being handled by each key case. It also doesn’t respond to the keypress immediately (i.e. no action happens until the first timer tick). This answer to Holding Arrow Keys … Read more
Use pygame.KEYDOWN and pygame.KEYUP to detect if a key is physically pressed down or released. You can activate keyboard repeat by using pygame.key.set_repeat to generate multiple pygame.KEYDOWN events when a key is held down, but that’s rarely a good idea. Instead, you can use pygame.key.get_pressed() to check if a key is currently held down: while … Read more
If you’re only interested in the example keys you mentioned, the keydown event will do, except for older, pre-Blink versions of Opera (up to and including version 12, at least) where you’ll need to cancel the keypress event. It’s much easier to reliably identify non-printable keys in the keydown event than the keypress event, so … Read more
You can’t change the character or key associated with a key event, or fully simulate a key event. However, you can handle the keypress yourself and manually insert the character you want at the current insertion point/caret. I’ve provided code to do this in a number of places on Stack Overflow. For a contenteditable element: … Read more
Attach to the Window’s Event After the control is loaded, attach to the Window’s KeyDown event (or any event) by using Window.GetWindow(this), like so: The XAML <UserControl Loaded=”UserControl_Loaded”> </UserControl> The Code Behind private void UserControl_Loaded(object sender, RoutedEventArgs e) { var window = Window.GetWindow(this); window.KeyDown += HandleKeyPress; } private void HandleKeyPress(object sender, KeyEventArgs e) { //Do … Read more
Figured it out by testing all the stuff by myself. Couldn’t find any topics about it tho, so I’ll just leave the solution here. This might not be the only or even the best solution, but it works for my purposes (within getch’s limits) and is better than nothing. Note: proper keyDown() which would recognize … Read more
Another approach (no plugin needed) is to just use .ctrlKey property of the event object that gets passed in. It indicates if Ctrl was pressed at the time of the event, like this: $(document).keypress(“c”,function(e) { if(e.ctrlKey) alert(“Ctrl+C was pressed!!”); });
I was having the exact same problem. I considered the answer @Snarfblam provided; however, if you read the documentation on MSDN, the ProcessCMDKey method is meant to override key events for menu items in an application. I recently stumbled across this article from microsoft, which looks quite promising: http://msdn.microsoft.com/en-us/library/system.windows.forms.control.previewkeydown.aspx. According to microsoft, the best thing … Read more
