KeyDown : recognizing multiple keys
You can check the modifiers of the KeyEventArgs like so: private void listView1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Up && e.Modifiers == Keys.Control) { //do stuff } } MSDN reference

jQuery key code for command key
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.
onKeyDown event not working on divs in React
You should use tabIndex attribute to be able to listen onKeyDown event on a div in React. Setting tabIndex=”0″ should fire your handler.
Removing the delay after KeyDown event?
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
How to use pygame.KEYDOWN to execute something every time through a loop while the key is held down?
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
Cancel the keydown in HTML
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
OS X: Detect system-wide keyDown events?
If you are okay with a minimum requirement of OS X 10.6+, and can suffice with “read-only” access to the stream of events, you can install a global event monitor in Cocoa: Cocoa Event-Handling Guide: Monitoring Events. If you need to support OS X 10.5 and earlier, and read-only access is okay, and don’t mind … Read more
DataGridView keydown event not working in C#
Whenever a cell is in edit mode, its hosted control is receiving the KeyDown event instead of the parent DataGridView that contains it. That’s why your keyboard shortcut is working whenever a cell is not in edit mode (even if it is selected), because your DataGridView control itself receives the KeyDown event. However, when you … Read more
Changing the keypress
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
Python method for reading keypress?
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
