Keydown and keypress events gives different keyCode
javascript,javascript-events,keypress,keydown,keycode
stackoverflow.com/questions/1367700/… explains it well. keydown is only tracking the key itself, not the state of the key. If you press 'A' KeyDown generates a KeyCode of Keys.A and if you press 'shift-A' you also get a KeyCode of Keys.A.
pygame - Key inputs not working in if not syntax
You need to completely rethink your approach. There are 2 good ways of doing key-based input. 1) Have a flag for each key, set it on KEYDOWN, and unset it on KEYUP. 2) Use the currently-pressed keys dictionary that Pygame provides. Then you can say stuff like "if keys["UP"]:". This...
keyDown() Not working Processing
This will won't work without draw function. Also you are declaring new local variable ready inside keypressed() this is bad mistake. Try move your drawing code from "keyDown()" into "drawing" like this: void draw() { if (ready == false) { background(#FFFFFF); //This is needed for redrawing whole scene fill(#FFFFFF); rect(350,...
Allow number and paste in input text box
You can try HTML5 input event: $('.onlyNumType').on('input', function(e) { // Beware, this will get called even if user hits `CTRL+V`! // In a nutshell, this will be triggered every time input changes. }); However, note that setting value programmatically like $('.onlyNumType').val('Hiya!') will NOT trigger this event....

How to filter keydowns with rxjs?

Keydown event Javascript?
You need to cancel the event! event.preventDefault(); Just make sure to only do that when you're submitting the form - it'd be very easy to accidentally nuke all ability to type in the textarea at all ;) Also, as a usability hint, I would suggest adding && !event.ctrlKey && !event.shiftKey...

Remove one-sample capture delay in .keydown()

Keydown Eventhandler Process

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...

Execute action after pressing the keyboard
I believe you want .offset().top instead of .position().top. $(window).on('keydown', function (e) { if (e.which != 40) return true; e.preventDefault(); var posicao = $('.homeBaixoRodapeTexto1').offset().top; $('html, body').stop().animate({ scrollTop: posicao }, 1500); }); You have to be real careful with this. You're essentially breaking navigation with the keyboard. Here's a small demo: http://jsbin.com/xecapoyu/3/edit?js,output...

Pass KeyDown event to other control
Any reason you can't just pass the event onto the "child control" ? Below example is KeyPress but the same idea applies for KeyDown //Parent Control Visible private void textBox1_KeyPress(object sender, KeyPressEventArgs e) { richTextBox1_KeyPress(sender, e); } //Child Control Hidden private void richTextBox1_KeyPress(object sender, KeyPressEventArgs e) { richTextBox1.Text += e.KeyChar.ToString();...

C# pressing key breaks movement of an object
